Drag flaky after dragging sub-elements

[andrewnicols]

Difficult to explain this one, so here's a quick jsbin: http://jsbin.com/IxaNuto/1/edit?js,output

Essentially, if you have a draggable list of items, which each contain draggable items, and you move the inner items around, and then the outer ones, there is sometimes some flaky stuff going on.

To replicate on the above jsbin:

• Move one of the inner items to a different out item
• Move it back to it's original location
• Now move the outer item

Expected result: It works

Actual result: The outer item that you dropped the inner item in and moved it out of is moved

Also seeing this with:

• Move inner item from section one to section two
• Move section two
• Move section one
