title: .hover doesn't work when hovered with draggable element
body: <p>Please pardon me for my bad english...</p>
  
  <p>situation:
  I've got a menu with submenus. 
  The submenus open when hovered. 
  (simple dropdown menu with ul's and li's)</p>
  
  <p>I've got a admin area from which i want to drag something in the menu.</p>
  
  <p>problem:
  When I drag something into the menu, it won't collapse, as if the .hover doesn't work
  Also the menu is sortable, because of the same problem you can drag subitems to mainmenu, but items from mainmenu can't be dragged to the subitems, because .hover doesn't work and the menu won't collapse.</p>
  
  <p>Is .hover ignored when you drag something onto it?</p>
