Marked test as flaky on Mac-wk2 https://trac.webkit.org/changeset/216552/webkit/
Comment 8 Ryan Haddad 2017-06-02 16:12:21 PDT
Marked test as flaky on iOS in http://trac.webkit.org/projects/webkit/changeset/217741
Comment 9 Ryan Haddad 2018-01-18 21:10:14 PST
Marking this as resolved since the test no longer seems to crash. It still fails and times out intermittently. Filed https://bugs.webkit.org/show_bug.cgi?id=181835 for that.
