Droppable that changes size during drag only respects original size
I have a page with a draggable and droppable. The draggable is a list of items and the droppables are folders. I added callback to the "over" event for the droppable so that when the draggable is over the folder, the items inside slide down. This increases the size of the droppable, but it still acts as if the droppable is the original size (i.e. the "out" event fires when the draggable is moved into the expanded area of the droppable, but outside the original area.
Is there a way to make the droppable respect the whole area of the droppable if it expands during the drag event?
