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: @@ -1,3 +1,5 @@ - -PASS Call register() on ServiceWorkerContainer owned by closed window. - +layer at (0,0) size 800x600 + RenderView at (0,0) size 800x600 +layer at (0,0) size 800x8 + RenderBlock {HTML} at (0,0) size 800x8 + RenderBody {BODY} at (8,8) size 784x0

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.
