      // We need to put this at the head of the commands so that it runs before

      // it's own settings command to the commands array which will change
      // views ajax_path back to views/ajax. If we don't fix this before views
      // runs it's ajax commands, the views ajax event won't get the facets in
      // the path and they'll be reset on exposed filter input.
