Droppable: leaving a greedy child fails to check if parent intersects

When leaving a greedy child, the parent droppable will receive an over event even if the draggable doesn't intersect.

For an example, see: http://jsfiddle.net/Y9BV9/1/

The blue draggable is too tall to ever intersect the red droppable with tolerance 'fit', but will intersect the green greedy child with tolerance 'pointer'. However, if you drag the blue draggable into the green droppable and then out, the red parent will get an over event on the way out of the green child.
