Dragging bug

[shaedys]

In the currrent demo (either MainGUI):
If you drag one item on top of each other in order to make a combination, then everything will work.

If first you drag your item to a different position than the starting one, and then try to combine that node with a different node, the two nodes will combine, but the positioning in the combination will be highly off (the node that was dragged to the other node will remain in place but now be attached)
