Description Alexey Proskuryakov 2018-12-01 13:42:22 PST
imported/w3c/web-platform-tests/service-workers/service-worker/register-closed-window.https.html used to be somewhat flaky, but starting November 27th, it fails roughly every other time.

It either fails or times out. The failure looks like this:

Probably started with resync in r238592. Chris, could you please take a look soon? This just resulted in a false rejection on commit queue.

I cannot reproduce with:
run-webkit-tests --repeat-each=200 -gf imported/w3c/web-platform-tests/service-workers/service-worker/register-closed-window.https.html

I suspect this may be caused by a test running right before it.

Marked test as flaky in https://trac.webkit.org/r239406
