Code

protected function bubble(GeneratedUrl $generated_url, array $options = []) {

  // Bubbling metadata makes sense only if the code is executed inside a
  // render context. All code running outside controllers has no render
  // context by default, so URLs used there are not supposed to affect the
  // response cacheability.
  if ($this->renderer
    ->hasRenderContext()) {
    $build = [];
    $generated_url
      ->applyTo($build);
    $this->renderer
