Summary: workaround for Firefox DOM-focus bug

Details:
DOM operations on a blurring element breaks the focus in Firefox. It's 
possible to reproduce the same bug with plain HTML and Javascript, I've 
attached a testcase at the bugreport. (Henry, do you've got an account 
for their Bugzilla to report the issue? Otherwise I need to create an 
account.)
To workaround that bug, I've added a new quirk "dom_breaks_focus" which 
is enabled for Firefox. If the quirk is enabled and DOM operations were 
performed (__shown property changes from 'true' to 'false'), focus() 
needs to be called manually on the "__focusedSprite". This is done at 
the end of "__textEvent()" to ensure that "onfocus" won't be send too early.
