* test(mobile-web): act on the HTML preview frame only once the browser routes input into it
Chromium runs the sandboxed preview frame in its own process. The rig decided an arm was
ready once the artifact had parsed, but the embedder can still be showing the frame's white
before its surface is composited, and still keep pointer input over the frame for itself
until it holds the frame's hit-test region. A click in that window landed on the
embedder's <iframe>, Playwright reported success, and the arm waited for a navigation
that never came (or read white as pixelBefore).
The rig now waits for the artifact's paint before reading pixelBefore, and before acting
moves the pointer over the frame until the embedder stops receiving it.
* test(mobile-web): name the arm in the input-routing timeout and trim history comments
* test(mobile-web): click the drawer chip once it is actionable, and honour the wait timeouts
* test(mobile-web): say why the drawer trial click stays, and report a failed open with page errors
* fix(mobile): preserve agent icons across stacked routes and tab updates
Closes#31939
* fix(renderer): address review feedback on mobile agent icon stability
* fix(renderer): fall back to customTitle when saved leafTitle is blank
* Keep mobile agent icons painted across retained routes
Use instance-specific OMP gradients and preserve bundled icon fallback during web image reload failures. Add a real mobile-web route-retention pixel regression.
