Code

protected static function isAjax() {

  // return (\Drupal::request()->get(MainContentViewSubscriber::WRAPPER_FORMAT) === 'drupal_ajax');
  //
  // ISSUE:
  // For nodes with computed elements there is a duplicate
  // _wrapper_format parameter.
  // (i.e ?_wrapper_format=html&_wrapper_format=drupal_ajax)
  // WORKAROUND:
  // See if _wrapper_format=drupal_ajax is being appended to the query string.
  $querystring = \Drupal::request()
    ->getQueryString();
  return strpos($querystring, MainContentViewSubscriber::WRAPPER_FORMAT . '=drupal_ajax') !== FALSE;
