Example URL:
http://atfe.fmworld.net/at/sp/arrows_theater/

Steps to reproduce the problem:
1. Open Browser,enter http://atfe.fmworld.net/at/sp/arrows_theater/
2. Play any video.
3. Tap the full-screen button during playback.
4. Exit full-screen
5. Repeat step 3 & 4

What is the expected behavior?
It does not become a black screen during full screen playback.

What went wrong?
During video playback, after switching the screen between full screen & non-full screen several times, the play screen becomes black screen.

Did this work before? No 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? No
