Bug 186574 – REGRESSION (r232534): [macOS] LayoutTest media/video-buffering-allowed.html is a flaky failure

• Status: NEW
• Component: Media

[Ryan Haddad]

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?

[Ryan Haddad]

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