  Test that "MozDOMFullscreen:*" events are dispatched to chrome on documents that use DOM 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 MozDOMFullscreen:Entered and
  MozDOMFullscreen:NewOrigin are dispatched to chrome, targeted at the outer document.
  
  Then we request fullscreen in the inner document, and check that MozDOMFullscreen:NewOrigin
  is dispatched to chrome, targeted at the inner document.
  
  Then we cancel fullscreen in the inner document, and check that MozDOMFullscreen:NewOrigin is
  dispatched again to chrome, targeted at the outer document.
