Perfomance issues with FireFox #382

I have stumbled upon a serious performance issue with select2. We have a rather complex page with many elements on it. The degradation in performance is considerable - upto 4 seconds to simply unfold a select box!

I have tracked down the culprit for this:
select version 3.1 select2.js

line 173:
$(document).delegate("*", "mousemove", function (e) {
replacing * with body improves a lot

line 481:
$(document).delegate("*", "mousedown touchend", function (e) {
Same thing - replacing * with body helps a lot.
