  foreach ([

  // Chances are entity_view, or Views flattens out the expected render array.
  // Or a drupal_render() is called too early, or just string passed.
  // Applies to thumbnail caption as well in case bypassing the API.
  foreach ([
    'slide',
    'caption',
  ] as $key) {
    if (!empty($variables['item'][$key]) && is_string($variables['item'][$key])) {
      $variables['item'][$key] = [
        '#markup' => $variables['item'][$key],
      ];
    }
  }

  // With clones, regular CSS :nth-child will fail to style uniquely, add delta.
  $variables['attributes_array']['class'][] = 'slick__slide slide slide--' . $variables['delta'];
