Bug 72381 – media-blocked-by-willsendrequest.html is flaky

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Tony Gentilcore]

The media/media-blocked-by-willsendrequest.html test has been flaky across all chromium platforms for as far back as we have history. My guess is that the flakiness isn't limited to chromium, though. When the test fails, we are missing the following two lines of output:
EVENT(loadstart)
EVENT(error)

From the symptoms, my best guess is that the test is trying to run before the video's loadstart. 

Eric, assigning to you just because you are the test author and I don't want to leave this ownerless. Please feel free re-title if this is chromium specific and/or bounce back to me for any reason.

I think your guess is correct. I believe that the test passes on other platforms but fails on chromium because the chromium media engine takes longer to start up so the widow's 'load' event is fired while the media events are in the queue waiting to be dispatched.

I will change the test to not finish until all required events have been handled.
