This is only tangentially related, but why in the drag and drop mode the coordinates for DRAG_DONE event are completely bogus when drop happens over a non-accepting target?


{event=DRAG_EXITED, x/y=(52, 32), screen=(1022, -1340), scene=(477, 71)}
{event=DRAG_EXITED_TARGET, x/y=(52, 32), screen=(1022, -1340), scene=(477, 71)}
{event=DRAG_DONE, x/y=(0, 0), screen=(0, 0), scene=(0, 0)}
