> At the end of a drag operation the Mac Glass code sends out a DRAG_DONE event using the operation mask tracked in the GlassDragSource to determine the final transfer mode. That mask is only updated when a window in the JavaFX app is the drop destination. If the drag moves to an external destination the mask is set to NONE. If the drag terminates in the external destination that NONE forms the basis of the transfer mode sent via the DRAG_DONE event.
