Str:

1. Open a page containing a Flash object; e.g. http://federalstudentaid.ed.gov/mystory/
2. Move to the Flash object and press enter.
3. Try to cursor around the Flash content.
   Expected: You should be able ot cursor around the Flash content.
   Actual: A useless window object gets focus and you have to fiddle with focus to read the content.

Originally fixed in be88fc4 (#775), but broke in 2013.1, probably due to 0b1f669 (#2454).
