    return;
  }

  // In TourViewBuilder.php a container is rendered, this container has
  // children attribute with the total count. If the count of these children
  // is 1, we can unset it. We don't want to show 1 of 1 count.

        // So we found arguments for tour_progress. This is an array consisting
        // of [ '@tour_item' => integer 1, '@total' => integer 1 ]. If we have
        // a total of one. We can unset it, we don't need a 1 of 1 count.

        // We can break out the foreach.
