public function hasUrl($args = NULL, $display_id = NULL) {
  if (!empty($this->override_url)) {

  }

  // If the display has a valid route available (either its own or for a
  // linked display), then we can provide a URL for it.
  $display_handler = $this->displayHandlers
    ->get($display_id ?: $this->current_display)
    ->getRoutedDisplay();
  if (!$display_handler instanceof DisplayRouterInterface) {

  // not be available yet in some instances when editing a view and doing
  // a live preview.
  $provider = \Drupal::service('router.route_provider');
  try {
    $provider
      ->getRouteByName($display_handler
