Source/WebKit/blackberry:

Fix exit fullscreen problem for elements in iframes. The
exitFullScreenForElement() call is passed a null element in
this case, instead of the original element which entered
fullscreen. If you look in Document.cpp you can see the
exitFullScreenForElement() call being made on the topDocument
(which has a null m_fullScreenElement) instead of the iframe's
document.

The Chromium and Windows ports get around this problem by
storing either the fullscreen element or its frame during
enterFullScreenForElement(), so I will bring the BlackBerry port
in line with this. See also bug 89817.
