This problem was discovered in the BlackBerry port during manual testing of fullscreen video at:
http://w3schools.com/html5/tryit.asp?filename=tryhtml5_video_all

The video element is in an iframe, and exiting fullscreen resulted in a crash. The exitFullScreenForElement() call was being made on the topDocument (which has a null m_fullScreenElement) instead of the iframe's document.

I also found 3 lines of dead code that I propose removing to reduce confusion, and a missing "else" statement.
