    // Allow only details elements that are directly after the warning header
    // or each other. There is no guaranteed wrapper we can rely on across
    // distributions. When there are multiple warnings, the selectors will be:
    // - h3#warning+details summary
    // - h3#warning+details+details summary
    // - etc.
    // We add one more selector than expected warnings to confirm that there
    // isn't any other warning before clicking the link.
    // @todo Make this more reliable in
    //   https://www.drupal.org/project/drupal/issues/2927345.
