    dash: Restore icon's expected DND behavior
    
    Commit ff3d32dd186fa added a custom DashIcon subclass that disables
    all DND methods from ancestors, including canceling the context
    menu timeout and emitting the overview's item-drag-begin signal.
    
    All we want is opting out of the parent's scale-and-fade behavior,
    so override those methods instead.
