Hover on column is not removed when leaving the tree node

[Andries-Smit]

Hover class is only removed, when the cursor is moved to the next item.

Expect the hove to be removed whenever the move is not above the item.

Maybe it should be removed on the "mouseleave" event, but I am not sure if this will break the dnd

Adding a live connect wil do the trick..
