imported/w3c/web-platform-tests/content-security-policy/frame-ancestors/frame-ancestors-from-serviceworker.https.html

This test is flaking on iOS. History shows that around r255423 this test changed from a flaky crash to a flaky failure. I am unsure if this should be considered a regression or not.

Comment 2 Truitt Savell 2020-02-11 10:51:09 PST 
This test was last synced in https://trac.webkit.org/changeset/254133/webkit which doesn't line up with when this test went from crashing to failing.
Comment 3 Truitt Savell 2020-02-11 10:52:02 PST 
This test is not reproducing locally by running the test in iterations.
Comment 4 Truitt Savell 2020-02-11 11:04:34 PST 
Marked this test as failing while it is investigated: https://trac.webkit.org/changeset/256321/webkit
