jQuery.event.dispatch should remove window.event

[snandy]

jQuery use addEventListener/attachEvent to add event handler. when use addEventListener, the event object will pass in handler's first argument.

attachEvent is the same as addEventListener when get the event object in IE6/7/8.

So, in the method jQuery.event.dispatch, the first line

event = jQuery.event.fix( event || window.event );

should modify as

event = jQuery.event.fix( event );

see testcase in IE6/7/8: ​http://jsfiddle.net/aLaD3/1/

By jove, I think you're right! This is leftover from the original "Dean Edwards" code which hooked events via the .onclick() etc. properties. It was removed in jQuery 1.2, back in 2007. ​http://code.jquery.com/jquery-1.1.js
