Keep target element CSS position

[noup]

We're enabling jquery-udraggable in a div with "position:fixed" (it's fixed so its position doesn't change as we scroll the page). However, jquery-udraggable overwrites the position to "absolute".

Maybe the plugin should assume that the correct style must already be present in the target element, and not enforced by the plugin? In that case, this line would be deleted:
