Bug when Drag on li with Internet Explorer 8

Bug when Drag on li with Internet Explorer 8


I use ui.draggable on a tree (<ul ><li><div>...</div></ul>).
I put the drag on the div element.
Try it with Internet Explorer 8 and you will see that there are some
problems of display with the clone of the dragged element.
Is it a bug from ui.draggable ?
Thanks
