Use the upstream owner-settlement API and publish nested command output at
the shared completion boundary. Inspector callbacks can already publish the
pending prefix while an owner remains paused; fence the concrete published
tail even when settlement has no new batch. This keeps beforeunload output
ahead of navigation fetch without closing the suspended command recorder.
Include before-fetch messages and completion details in the existing
paused-navigation regression assertions, and format replayed imports.
Validation: cargo fmt --all; workspace/all-target/all-feature Clippy with
warnings denied; nextest 20,797 passed, 16 skipped, 32 threads, zero retries.
Both paused beforeunload regressions also passed 10 consecutive rounds.
Run tree beforeunload from the existing Inspector scope so navigation can
start its request while the old script remains paused. Bind the active
Page per owner-task poll and preserve the beforeunload output prefix and
navigation fence without completing a suspended Runtime command.
Keep document-replacement termination pauses internal while preserving
real output and balancing pauses already reported to frontend sessions.
Keep intentional pagehide/unload callbacks debuggable during replacement.
Cover root/child lifecycle ordering, 204 recovery, resumable unload,
multiple sessions and cancellation between pause notification and loop entry.
Run browser-initiated main-document checks through the existing asynchronous
lifecycle scheduler before Fetch interception or network loading. Project the
source turn first, reject superseded navigation tokens, and share navigation
finalization so failed checks retain the committed document and release state.
Foreground DevTools callers remain pending through the check and load, preserving
typed navigation results and the captured target owner.
Keep beforeunload and commit unload commands out of nested non-V8 Page-agent
dispatch while the owner is debugger-paused. Cover real navigate/reload/history
responses, retained documents, pause/resume, supersession, and Fetch ordering.
Join child candidates to their active top-level Document's queue in connection
order. Revalidate ownership and ancestor fragments when flushing, and preserve
blocked candidates until their own Document's stylesheet readiness settles.
Construct focus transitions in the target Document's realm using the intrinsic
FocusEvent with its view, without consulting author constructors or inherited
initialization getters. Cover queue ownership, retirement, policies, stylesheet
wakes, and cross-realm focus event behavior.
Keep submit and formdata events synchronous while navigation runs as a
DOM-manipulation task. Capture the request, submitter, target and history
handling; coalesce replaced submissions without extra task turns.
Preserve popup POST requests, cross-origin and sandbox boundaries, and
javascript URL replacement ordering. Follow form navigation that starts
during document creation and cover reentrant, adopted and same-URL forms.
Validation: cargo fmt --all; workspace all-target/all-feature clippy with
warnings denied; cargo nextest run --no-fail-fast (20,002 passed, 16 skipped).
Two additional official WPT cases pass with no passing-case regressions
across the form and Navigation API suites.
Allow top-level navigation owner actions from the current Document through
the in-flight navigation gate so they can cancel the previous request.
Keep exact scheduler predecessors and Page residence validation in place.
Cover an unresponsive first request replaced by page JavaScript without
further client commands, and ensure only the replacement enters history.
Carry committed renderer history through browser navigation requests and
restore structured state, entry identities, and activation before new
Document scripts execute. Read the latest committed source entries when
creating the destination so state updates made during a pending response
are retained.
Keep browser traversals aligned with native Document identities, rebuild
private history ordinals for restored top-level entries, and use native
entry indices for fragment mutations after a cross-origin history prefix.
Cover structured-state restoration, pending-navigation source updates,
fragment indices, browser-owned back/forward traversal, and same-Document
realm and element preservation after WebDriver history restoration.
execCommand("copy") previously returned the user-activation flag without
firing an event or updating the clipboard. Dispatch trusted beforecopy and
copy events, honor cancellation, and copy the receiver document's selection.
Keep text-control selections per document across focus changes and reject
nested editing commands per native document. Share Window activation state
with navigator.userActivation so copying remains available after the
activating call and expires without clearing sticky activation. Read fresh
layout for DOM selection text, preserve preformatted whitespace, and use
the browser profile's clipboard line endings.
Add nine regression tests and correct the BiDi activation regression test.
Validate 38 copy-command cases, 38 existing native shortcut cases, and nine
activation-state cases against Chromium. The copy-event WPT and all 32
selection line-break subtests now pass, with no regressions in 65 WPT cases.

Query dialogs on the addressed Page when waiting for navigation lifecycle milestones. Allow independent page load completions to advance while another page has a blocked load.
Cover normal and eager navigation with gated two-window regressions, eager recovery after accepting an alert, and dialog ownership across DevTools attachments.
While a JavaScript dialog is open, the scheduler no longer waits for the
page load to finish. WebDriver Classic commands using the normal and eager
page load strategies now return, and the session stays usable.

Enforce document and Location authority at realm boundaries, preserve Window-owned timer and Service Worker completion state across initial commits, and retire isolated-world IndexedDB handles without pinning the old realm.
Create script auxiliary Pages synchronously and let their CDP targets adopt
those exact Pages. Preserve Page and WindowProxy identity through document
navigation, sharing browsing-context names, opener references, message endpoints
and close state with related windows.
Commit browser responses into the existing Page with exact document admission,
cancellation and failure disposition. Capture accepted navigation origin, base,
policy, storage and referrer, preserve auxiliary history and restore related
browsing-context groups without issuing duplicate popup requests.
Reuse the initial same-origin Window while replacing its Document, and centralize
Document owner transitions, descendant retirement and Inspector publication.
Give related Pages independent Inspector routes and shared per-Page startup
pause state, route isolate foreground work through surviving Pages, and cache
cross-origin Window functions in each accessing realm with receiver-aware access.
Cover actual popup state, navigation and parser rebinding, accepted environments,
history, cross-origin access, multiple frontends, cancellation and task retirement.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast.
Track each window's selected tab and browser focus independently of protocol
page routing. Keep window bounds, adjacent-tab close selection, discovery and
target metadata consistent with their owning windows and documents.
Queue renderer activity updates outside the CDP actor, preserve their output
fences and remember admitted activity so focus reversals survive a busy page.
Cover window selection, focus-event state and busy-context activation.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast.
Hide native scrollbars and automatic gutters while preserving scrolling and explicit stable gutters. Require layout mode and retain the setting across navigation, frames, and protocol sessions.

Use the shared frontend admission and native terminal path for renderer
configuration. Keep Browser replay policy on its captured owner, record
admitted idle state, and project a fallback only if publication lost.
Verify mixed native replies precede later Inspector replay and that
isolate-entering configuration waits for the suspended owner to resume.
Migrate node queries, edits, focus, files, remote objects, DOMDebugger and
Autofill to renderer-owned terminals. Freeze document notifications and
object registry updates at the producer boundary, preserve object aliases,
and keep isolate-entering lookup chains on the owner turn.
Run native lookups and bounded continuations through the shared terminal
path. Publish stylesheet inventory notifications before ready responses,
and preserve exact owner routing in direct Page test fixtures.
Use the parsed fixture and stylesheet notification boundary to verify
Page and CSS commands preserve their independent isolate-entry requirements.
Share terminal authority with Inspector and publish ready native replies
after their renderer facts, independently of adapter polling. Keep typed
internal completions separate and settle caches against the exact residence.
Define exhaustive backend entry requirements for nested Main dispatch and
release Main and IO admission at backend entry. Bind native continuations
and preserve their owner lifecycle before terminal projection.
Migrate Page and DOMSnapshot through the generic operation boundary,
including live tree URLs, initial DocumentLoader identity, document capture
and isolated worlds. Cover cancellation, retirement and pause ordering,
and release held popup fixture routes before awaiting initialization.
Publish existing contexts, console messages and exceptions before the
Runtime.enable terminal for pages and workers. Check the enable boundary
without a compensating command, and retain deferred reply progress.
Give document decoding explicit HTML, XML, and text declaration policies.
XML ignores HTML meta elements, retains BOM and transport charset precedence,
and selects an initial XML declaration or UTF-16 signature before its UTF-8
default. Keep partial declarations and signatures buffered across chunks.
Cover conflicting meta declarations with and without an XML declaration,
including main documents, iframes, and external raw input. Adapt seven
Chromium XML/XHTML navigation scenarios and three decoder boundary tests
from Chromium a03603fe9af6230a12f1b2fb2c18a7d003a0d937; source paths are
recorded next to the tests. These include KOI8-R script inheritance, CP1251
XML, BOM-less UTF-16, supplementary Unicode characters, and BOM boundaries.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- XML and Chromium regression tests passed.
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast:
18,980 passed, 16 skipped.
Keep network XML response bytes intact through the existing raw-body renderer
path. Decode both network and external XML bodies with the shared response
decoder, then install the selected encoding before document bootstrap.
Remove the obsolete ready-body capture variant used by the old XML path.
Cover matching main-document and iframe text, namespaces, and characterSet for
Atom, RSS, and text/*+xml responses with Windows-1252 headers, XML declarations,
and UTF-16LE/BE BOMs. Exercise the external input as single-byte chunks and
verify that BOMs override a conflicting transport charset.
Validation:
- Before the fix, the network regression returned caf� / UTF-8 instead of
café / windows-1252.
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- Six focused XML tests passed.
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast:
18,954 passed, 16 skipped.
Keep valid inherited text encodings ahead of heuristic detection while
preserving BOM, transport charset, and JSON default precedence. Share the
response decoder between streaming main documents, asynchronous child
loads, data URLs, and blocking child snapshots.
Classify navigation XML MIME types independently of DOMParser's allowlist,
including +xml subtypes in parser routing and text exclusions. Add
regressions for inherited UTF-8, literal encoding declarations, XML
namespaces, and DOMParser rejection of navigation-only XML types.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast
18,952 passed, 16 skipped. Two existing timing tests failed under the
default concurrency, then passed individually and in the full run above.
Keep request identity and cancellation in Fetch while read tasks exclusively own response data. Match completions to the registered read instead of reinserting transfers or replying to navigations from I/O completion.
Retire superseded reads immediately, drain reads on Fetch disable, and preserve typed read errors. Cover delayed successes, failures, request reuse, cancellation, and debugger-paused supersession.
Centralize navigation dependency decisions for readiness probing and snapshot draining. Replacement actions can reach the owner that cancels the pending request even when earlier observations wait for that load, while exact owner authorization remains mandatory.
Keep retirement admission policy beside publication ownership. Extend coverage for stale owners, cancellation, reused frontend ids, duplicate terminals, and late results without reviving retired notifications or remote objects. The new queue regression fails before the scheduler fix.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast (18833 passed, 16 skipped on the final change set).
Only the current navigation can suspend renderer output; older jobs retain cleanup ownership without blocking the active document.
Retire target-owned request, auth and response interceptions on supersession, cancel streaming transports and reject stale body-read completion. Cover paused debuggers, overlapping navigations, target isolation and once-only terminal replies.
