Description Jacob Uphoff 2020-02-04 13:57:12 PST
imported/w3c/web-platform-tests/service-workers/service-worker/extendable-event-waituntil.https.html

This test has been a flaky failure for all visible history on debug and release 

I was able to reproduce the failure simply by running the test in iterations (ran 5000, got 50 failures)

History:

https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fservice-workers%2Fservice-worker%2Fextendable-event-waituntil.https.html&limit=50000
