Drag/drop with drop as position:fixed;


Can anyone tell me why the drag and drop UI won't let you use the
"dropper" as a position:fixed element. If you scroll the page, it
just uses the "dropper" div where it was before you scrolled, the
"dropper" box itself scrolls when you scroll, but the invisible drop
area which allows you to drop does not move.
