title: jQuery, Mouseleave not fired on container when moving cursor fast
body: <p>I've got a bit of a bug.
  Well, the code on jsfiddle speaks for itself, to provoke the bug move your mouse quickly over the red box (to one side or the other).</p>
  
  <p>A quick explanation:
  I have a list of items, when i hover them i show an overlay div on their positions, i bind an mouseenter on the list item, and an mouseleave on the overlay div, but if you move the cursor to fast, the mouseleave is never triggerd.</p>
  
  <p>Any ideas? Thanks! </p>
