    37643: Reset interrupt on key input in menu selection.
    
    We don't need to propagate the interrupt further as the interrupt
    causes the key to be empty, which will exit the widget.  We
    need to reset the condition as zrefresh() is now more sensitive
    to errors since 36416 / 32f5d3d8.
