The existing behavior does sound consistent at least. When a drag starts, the node "captures" the mouse and doesn't let go until the event concludes. This is the same as if the node had remained in the scene graph. Since the node is no longer in the scene graph, there is no hierarchy to bubble / filter / capture events in.
What other options are there which would also work? We could send a mouse drag ended, mouse release, etc to the node which has been removed from the scene graph and then start a new drag event at the current location. I'm guessing this is the behavior you were looking for?
