React Virtualized requires mouse movement

I have tried applying react-sortable-hoc to a react virtualized grid. When I drag something and then pause, all of the cells take up the area left by the old cell and no longer move.

jfrolich's comment here: https://github.com/clauderic/react-sortable-hoc/pull/326
demonstrates the same behavior

Start by reproducing the reported behavior with react-sortable-hoc applied to a react virtualized grid, then compare it with the behavior demonstrated in the linked pull request comment. Done means the grid cells retain their correct positions and continue moving when dragging pauses.
