How to avoid execution of "accept" function on each droppable element?
Hi,
here is example, where each ".plan" can be moved into each ".unit".
http://jsfiddle.net/3jvuqdu1/6/
Please drag ".plan#6" (F) from parent .unit (6) to its sibling (5) and see console log.
"accept" is executed on each ".unit" - not only on covered by draggable element.
Is it a bug or should I find new idea to restrict the set of calls of this function?
In real situation I have about 500 such constructed droppables with quite complex "accept" method. It significantly slows down dragging, especially on Firefox.
