Hi, I'm the Playwright bot and I took a look at the failing CI on this Chromium roll.

🟡 Nothing pins on this roll, but one macOS timeout I can't fully clear

Two of the three failures are known pre-existing flakes (one of them can't even be a Chromium roll — it's Firefox). The third is a bare 30s timeout on macOS-chrome with no prior history, so I can't call it either way.

Details

This is a Chromium-only roll to r1241 (README.md + version-badge/browsers.json bumps, no product code). So anything failing on Firefox/WebKit is by definition not caused by it, and the chrome MCP failures need cross-run evidence before I'll blame the roll. Results from the merge run (32412811801).

Pre-existing flake / infra

• [chrome] › mcp/config.spec.ts:203 › chromiumSandbox › --sandbox enables the sandbox (mcp-ubuntu-latest-chrome) — pre-existing, widespread failure, not this roll. In the results DB this test failed on ~28 other SHAs it can't be responsible for, across PRs feat(mcp): add browser_emulate_media tool and --color-scheme option #42244, fix(aria): annotate aria-hidden elements in AI snapshots #42268, feat(browserContext): add windowState option #42286, … feat(webkit): roll to r2355 #42337 and several push SHAs on main. It's been failing on mcp-ubuntu-latest-chrome continuously.

• [firefox] › mcp/cli-core.spec.ts:262 › click button with CSS selector (mcp-windows-latest-firefox) — flake, and a Chromium roll can't touch Firefox. Same test also failed on Firefox for PRs feat(webkit): roll to r2349 #42241 and feat(trace): split API requests into a separate network stream #42073 and on mainpush SHAs, unrelated to this change.

Uncertain

• [chrome] › mcp/cli-storage.spec.ts:48 › state-save saves to custom filename (mcp-macos-latest-chrome) — a bare Test timeout of 30000ms exceeded. (ran 30075ms), only on macOS-chrome. It passed on chrome under ubuntu and windows in this same run, and on every chromium bot. I couldn't find this test failing anywhere else in the results DB (0 prior failures across 742 chrome runs), so by the flake rule I won't call it a proven flake. The signature — a lone macOS timeout on a storage-state-save test that doesn't exercise the browser binary — leans runner hiccup rather than the roll, but I can't prove it. A re-run of the macOS-chrome MCP shard would settle it.
