Subject of the issue

noticed that when playing with H5 ranch, but apparently this happens with Jquery code and 2.1.0

Your environment

• 2.1.0, chrome

Steps to reproduce

open two.html
drag item from grid1 onto grid2 and push items around

Expected behavior

items restore back to initial location once item leaves or doesn't cause conflict

Actual behavior

keeps pushing items down and never restores it back

This also happens to a lesser degree when dragging new item to grid2
