    Bug 41410: Fix circuit display sizing hack for opening sub-menus.
    
    We only apply our hack on popupshowing and popuphiding if the event
    target matches the panel popup.
    
    We also add a FIXME note since the sizing hack is fragile.
    
    We also use the "hidden" attribute to hide the circuit instead of
    setting the inline "display" style.
