Extend the existing service-worker navigation test to check IndexedDB transaction completion and the saved value after a cross-site round trip. This covers the WebKit process-suspension bug fixed upstream in WebKit/WebKit#74082; no implementation change is needed.

Verified with npm run test -- page-goto.spec.ts page-history.spec.ts --retries=0 --reporter=dot --workers=6 (247 passed, 2 skipped), three repetitions per current browser (9 passed), npm run build, and npm run flint. The same test times out at the post-back IndexedDB read with WebKit r2359 selected through WKPATH.

Fixes: #42694

🟢 The reported failure is a pre-existing flake

Hi, I'm the Playwright bot. I compared the reported failure with this PR and refreshed CI history.

Details

The single failure in the latest posted report is not caused by this PR.

Pre-existing flake

• [firefox] › mcp/sse.spec.ts:196 › sse transport browser lifecycle (persistent) on mcp-ubuntu-latest-firefox: localStorage.a returns undefined instead of "42" after reconnecting to the persistent browser. The identical test and assertion failed on main, SHA 4d05531e1483, on October 28 (run), and on unrelated PR devops: run tests through a shared CI environment action #43735 that day (run). Both precede this PR. Refreshed CI history for this same test, project, and bot on October 22–29, excluding this PR, contains 3 failed runs and 176 passed runs.

This PR only extends tests/page/page-goto.spec.ts; it changes no browser implementation, MCP code, or shared fixtures. The changed service-worker/IndexedDB test passed on Chromium, Firefox, and WebKit in this PR's library-test run.

This verdict covers the reported failure. One macOS test-runner job was still running when checked.
