IE7 not dragging if position:absolute. drags only once otherwise.


I've been eagerly testing some of the new UI and I've run across a
problem with draggables in IE (7). Using the following HTML page, in
IE I cannot drag at all if the element is absolutely positioned. If it
is relatively positioned or not positioned at all, I can drag only one
time. Trying to drag the same element fails after the first time.
Needless to say, Firefox and Opera work great.
