It's a regression, I'm able to reproduce the issue since Firefox 12.a1 (see my screenshot).
On the current Nightly, when the bug is visible, the play button doesn't fade out and controls don't hide.

I can reproduce, and I see a probable culprit in the console, each time the big play button fails to hide:

I can't reproduce this using:
data:text/html,<video src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" controls></video>
on Windows 10 Nightly 2016-05-04. Paul, can you still repro this?
