http/tests/media/media-stream/get-display-media-prompt.html 

this test is a flaky failure on MacOS 

test is also flaky timing out 

I was able to reproduce the failure by running the test in iterations

Timeouts are seen throughout all visible history

No failures before 2019-11-05. First failure was with r252047, which was a media related change, but failures were not frequent enough to positively blame.

Let's track failures and timeouts together, because they started at the same time.
