To replicate:
1. Run test/tree
2. Change "Selection Mode:" to Single+Drag
3. Drag 'Ddd' up and over the "ccc button" and release mouse to drop
The drop is ignored.
FL_RELEASE is being sent to the tree's handle() method but it's being
ignored, probably because the release is inside the widget(). It should
be handled by the tree due an item being actively dragged.
