Mac WK2 EWS very frequently fails, claiming media/track/add-and-remove-track.html to be failing. But it's actually flaky. Quite obviously, it's caused by some other test doing Web Notification work.

It is very likely that the same issue happens on testers too, but we botwatched it away by marking affected tests in TestExpectations. But due to the nature of this failure, it can clearly happen on other tests randomly, and can migrate to other tests with time.
