'ajax' key defined twice

Hello.

I've found little mistake. Key 'ajax' has been defined twice in function ctools_access_ajax_edit

  $form_state = array(
    'plugin' => $plugin,
    'id' => $id,
    'test' => &$access['plugins'][$id],
    'access' => &$access,
    'contexts' => $contexts,
    'title' => t('Edit criteria'),
    'ajax' => TRUE,
    'ajax' => TRUE,
    'modal' => TRUE,
    'modal return' => TRUE,
  );

Here are two keys 'ajax' with the same value.
