This test is flaky crashing on Mac. It appears to have a regression point at r256910.


Crash log attached.

I have marked this test as crashing while this is investigated.
Comment 3 Alexey Proskuryakov 2020-02-29 13:01:53 PST
Seems more likely to be an ANGLE regression, r256784. Jason couldn't reproduce, but it's certainly happening on the bots.
Comment 4 Kenneth Russell 2020-03-01 10:58:17 PST
Most likely when a page is retrieved from the back-forward cache it's not reinitializing all of the ANGLE-related data structures. Need to catch this in the debugger.

Removed flaky expectation in https://trac.webkit.org/changeset/260873/webkit since the test has been consistently passing for the past few weeks.
