Serve the upstream long WAV and range stash resources with streaming writes, byte-range metadata, cancellation and exact path discovery. Cover custom methods, duplicate headers, stash isolation and shutdown.
Write .asis fixtures directly to the connection, preserving raw status lines, duplicate framing fields and malformed bytes. Bypass generated headers, pipelines, substitutions and HEAD body suppression as upstream wptserve does.
Remove the URL-based synchronous XHR repetition gate. Independent requests to the same resource must run normally, including failures followed by recovery, method changes and child-document requests.
Retain Error and WebAssembly CompileError/LinkError kinds when translating module failures into and out of the shared module tree. Cover cached graph failures and malformed Wasm import rejection, including author-replaced constructors.
Serve redirect-empty-location.py with a present empty Location header, fixed 302 status and no CORS grants. Respond before unused uploads complete and recognize only the supported resource references.
Index each row's cell range and row-group boundary to remove repeated
placement scans. Cache complete table measurement outputs, including
baselines, in an eight-entry LRU with layout cache invalidation.
Preserve caption minima, Flex table heights, percentage padding bases,
anonymous table behavior and the existing vertical layout path. Extend
the Chromium geometry fixtures and refresh the full WPT-cross case lists.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast: 18180 passed, 13 skipped
- WPT-cross all: 8779/12906 passed; table: 535/716 passed
- Table results unchanged by index/cache optimization; 28 full-run
differences checked twice per binary with no stable new regression
Reject service worker module graphs containing top-level await before instantiation or execution. Traverse evaluation dependencies, including synthetic Wasm imports, while excluding source-only edges. Cover direct and transitive await, cycles and ordinary async functions.
Determine visibility from registered browsing-context ownership and page activity. Reading contentWindow on a detached iframe must preserve its hidden state while defaultView continues to expose the synthetic Window. Cover nested detached documents, getter order, live child realms and popups.
Prefer the DOM wrapper creation context over the document default context when selecting a result realm. Keep Canvas TextMetrics in the isolated world and preserve separate default-world prototypes.

Expose V8 intrinsic instance prototypes from child WebAssembly constructors so native modules, instances and errors retain correct constructor and instanceof identity. Preserve realm isolation and prototype descriptors; cover compile, link and runtime errors plus author exceptions.
Move inline content that cannot fit beside floats to the first suitable slot,
and retain that clearance in CSS baseline and container-height calculations.
This places GitHub's full-width Show more activity button below its timeline.
Update Taffy to e4e8f77c for float segment extension and content-slot fallback.
Preserve whitespace collapsing around out-of-flow loading hints and cover
float placement, staggered heights, and pre/nowrap behavior in regressions.
Consume child-frame navigation before the Runtime.enable helper clears
collected events, avoiding an event-ordering race in the Fetch test.
Use a local connection-drop server to trigger nested worker script load
failure, removing external DNS timing from the asynchronous error-event test.
Preserve the constructor, event type, message, and filename assertions and
verify that the fixture receives the expected child script request.
Use collision-checked random UUIDs for object URL identifiers instead of a process-local counter. Reuse the existing UUID generation for Blob identity and cover URL format plus independent lifetime for multiple URLs referencing one Blob.
