Floated or fixed-width droppables not working

Floated or fixed-width droppables not working


Hi,
I've run into a strange problem using droppables. When my droppable
has a fixed width or is floated, the hover & drop events don't fire
when an appropriate draggables are dragged. If I simply remove the
width or float from my droppable, everything works fine.
Here's a running example: http://sandbox.wrkng.net/jquery-dragdrop-width-problem/
Is this a known issue? Is there a workaround that I'm not seeing?
Thanks in advance for any help.
