Description Russell Epstein 2019-08-15 16:10:43 PDT
The following layout test is flaky on iOS

imported/w3c/web-platform-tests/service-workers/service-worker/ready.https.html

Steps to Reproduce:

run-webkit-tests --ios-simulator --no-retry --no-sample-on-timeout imported/w3c/web-platform-tests/service-workers/service-worker/ready.https.html --iter 10

This test has been known to be flaky for a long time, tracked in webkit.org/b/181837; however, the test is now failing in an additional way. It appears that the test harness is timing out (see Diff below).
