    appDisplay: Update folder dialog field before ungrabbing
    
    Noticed while working on customizable folders. Calling GrabHelper.ungrab()
    ends up calling FolderDialog.popdown(), but at this poind the '_isOpen'
    field isn't updated yet, so we end up calling popdown() twice.
    
    Update the '_isOpen' field before ungrabbing.
