                OS: Unspecified

The following layout test is flaky on macOS Debug WK2

imported/w3c/web-platform-tests/service-workers/service-worker/fetch-request-fallback.https.html

Probable cause:

Unknown.

Flakiness Dashboard:

The diff shows a harness timeout. The test seems to normally finish in under 5 seconds.
