I have a div which contains a list of elements. Each element can
receive other draggable elements. The div is scrollable to accomodate
longer lists as I want a footer below the div to remain visible at all
When scrolling is not enabled (short lists), the drag and drop works
fine. Once scrolling is enabled though (longer lists) I find that I
have to drag elements to what would appear to be the absolute
coordinates of the target “receiving” element - that is, its position
if scrolling were not enabled.
