  // @todo Decide if \Drupal\views_ui\Form\Ajax\ViewsFormBase::getForm() is
  //   perhaps the better place to fix the issue.
  // \Drupal\views_ui\Form\Ajax\ViewsFormBase::getForm() drops the current
  // form from the stack, even if it's an #ajax. So add the item back to the top
  // of the stack.
