protected function addContextualLinks(&$output, $block_type = 'block') {

  // Do not add contextual links to an empty block.
  if (!empty($output)) {

    // Contextual links only work on blocks whose content is a renderable
    // array, so if the block contains a string of already-rendered markup,
    // convert it to an array.
    if (is_string($output)) {
      $output = array(
        '#markup' => $output,
      );
    }
