  // See views_ui_ajax_get_form() for how this affects #ajax.
  // @todo To remove this and allow the form to be cacheable:
  //   - Change $form_state->get('view') to $form_state->getTemporary()['view'].
  //   - Add a #process function to initialize $form_state->getTemporary()['view']
  //     on cached form submissions.
  //   - Use \Drupal\Core\Form\FormStateInterface::loadInclude().
