Description Ryan Haddad 2018-06-12 14:25:14 PDT

media/video-buffering-allowed.html was flaky since it was added in https://trac.webkit.org/changeset/231817/webkit, but after this https://trac.webkit.org/changeset/232534 it is failing very frequently on macOS debug bots.

Jer, would you please take a look at this one?

Comment 2 Ryan Haddad 2018-06-12 14:41:39 PDT

Marked test as flaky in https://trac.webkit.org/r232776 since I can't cleanly roll out both changes.
