   Test that "MozEnteredFullscreen" is dispatched to chrome on documents that enter fullscreen.

   Test Description:

   This chrome window has a browser. The browser's contentDocument (the "outer document")

   in turn has an iframe (the "inner document").

   We request fullscreen in the outer document, and check that MozEnteredDomFullscreen is

   dispatched to chrome, targeted at the outer document.

   Then we request fullscreen in the inner document, and check that MozEnteredDomFullscreen

   is dispatched to chrome, targeted at the inner document.

   Then we cancel fullscreen in the inner document, and check that MozEnteredDomFullscreen is

   dispatched again to chrome, targeted at the outer document. This still happens, since the

   outer document's domain was never approved for fullscreen.
