I've got tableViews, 2 of 'em actually, that support dropping items.
One does NSTableViewDropAbove and the other does NSTableViewDropOn.
Both exhibit the same problem, a residual visual indicator if the
drag leaves the target while still hovering over a valid proposed row
which has responded with a NSTableViewDropOperation.
draggingExited doesn't give me access to the proposed row.
Even if it did, there is no NSTableViewDropOperation which would
allow me to say: None.
How do I clean up this stray (boxed row) or (line indicator) when the
drag source leaves the tableView?
