Hi, I'm the Playwright bot and I took a first look at the CI failures on this Firefox roll.

🟢 Both failures are pre-existing, not caused by this PR

The Android test fails on every run, main included. The Firefox macOS aria test was already flaky on this bot before this roll.

Details

This PR only touches the Juggler PageAgent.js, the Firefox bootstrap.diff and browsers.json, so the Android failure can't come from it. The Firefox one is in the right engine, but the same test on the same bot was already failing on main and on unrelated PRs.

Pre-existing flake / infra

• [firefox-library] › library/inspector/cli-codegen-aria.spec.ts:87 › should update aria snapshot highlight (firefox-macos-15-large): known flake. In the test-results DB it failed in 17 of 309 runs after retries, and failed on at least one attempt in 61, on main and on unrelated PRs (feat(chromium): roll to r1241 #42340, fix(android): include the from point in the swipe path #42349, feat(chromium): roll to r1243 #42434, feat(webkit): roll to r2357 #42437, feat(firefox): roll to r1549 #42767, feat(chromium): roll to r1247 #42915). It fails only on this macOS bot and passes on the other Firefox bots in this report.
• [android-page] › page/page-set-content.spec.ts:57 › should include shadow roots: already broken, not a flake. It failed in 46 of 46 recorded runs, on main and on feat(webkit): roll to r2366 #42879, feat(webkit): roll to r2367 #42898 and feat(chromium): roll to r1247 #42915. It runs on Android Chromium, which this PR doesn't touch.

The 39 flaky entries include the browsercontext-cookies-third-party.spec.ts Partitioned; cookie tests on every Firefox bot. All of them passed on retry, so I didn't triage them. Because they're Firefox-wide they're worth a look in a roll PR, but they aren't failing.

I couldn't top up the DB with the newest runs (the GitHub API returned a 500), so this PR's own run isn't included in the history above.

Reported an iframe-to-parent focus regression in #43280, with a minimal reproduction and build bisect. With the Playwright client fixed at 1.64.0, r1552 passes and r1553 fails all three scenarios in both headed and headless mode on macOS arm64. This places the regression in the build rolled here; the exact C++ cause is not yet confirmed.
