There's a menu_overview_form item for the popup_admin module. I assume this is a broken admin/build/menu popup support? Here's a work in progress to fix it:

  // Menu Module
  if (module_exists('menu')) {
    $popups['admin/build/menu'] = array(
      // Tabs
      '#tabs-wrapper a:contains('. t('Add menu') .')',
      '#tabs-wrapper a:contains('. t('Settings') .')' => array(
        'noUpdate' => TRUE,
      ),
    );
    $popups['admin/build/menu-customize/*'] = array(
      // Tabs
      '#tabs-wrapper a:contains('. t('Add item') .')',
      '#tabs-wrapper a:contains('. t('Edit menu') .')' => array(
        'noUpdate' => TRUE,
        'updateTitle' => TRUE, // Doesn't work?
      ),
      // Edit, delete and reset items
      'table#menu-overview td:nth-child(5) a, table#menu-overview td:nth-child(6) a',
    );
  }

Needs #385432: Aggregator Module Support for the $popups array.
