That method doesn't work for focus. Focus doesn't bubble in IE, and
you have to use activate. I could check if activate is present and
use that, but it's backwards. But it seems like this is what is done
for XHR:
return window.ActiveXObject ?
new ActiveXObject("Microsoft.XMLHTTP") :
new XMLHttpRequest();
Any other ideas?
