Description Truitt Savell 2018-07-18 10:05:13 PDT
The following layout test is flaky on MacOS WK2

http/wpt/service-workers/update-service-worker.https.html

Probable cause:

Issue seems to have been around for a while. the tests are very intermittent in their timeouts. They seem to happen more often on Release builds

New results history link: https://results.webkit.org/?suite=layout-tests&test=http%2Fwpt%2Fservice-workers%2Fupdate-service-worker.https.html

It appears that this is a rare flake, happening most often on iPadOS Debug.
