  // The following line reloads the 'dialog' and 'flagging_dialog' libraries.
  // Why? Because there's a bug in Drupal/DialogAPI:
  //
  // When the JavaScript aggregator is turned on, DialogAPI (in
  // dialog_ajax_render_alter()) tells the browser to load drupal.js and
  // ajax.js as well, and this blows away the additions dialog.js did to some
  // data structures there (Drupal.{theme,ajax}.prototype). So we re-introduce
  // these additions.
  //
  // See http://drupal.org/node/XXXX
