    modalDialog: Ensure to let focus manager handle key events
    
    Since the grab no longer lets events bubble up to the stage unstopped,
    we should be forwarding the key events that bubbled up to the dialog
    to maybe cycle focus.
    
    Fixes focus cycling on keyboard navigation inside dialogs.
