    dnd: Emit drag-end in after snapback complete
    
    Emit the signal at the correct time to take action
    on snapback (i.e. after the end of the snapback animation).
    
    Add a boolean to the drag-end signal saying whether it was accepted,
    which ensures consumers know whether the drag was successful.
