That's not completely certain. Many Web pages use a function that  
abstracts the difference between addEventListener and attachEvent, so  
it's possible that there are existing Web pages which add a "focusin"  
handler with addEventListener in non-IE browsers, but behave properly  
because it is never dispatched. I don't know whether such pages  
actually exist, but I would not be so quick to rule it out.
