Code

public function view(EntityInterface $entity, $view_mode = 'full', $langcode = NULL) {
  $build_list = $this
    ->viewMultiple([
    $entity,
  ], $view_mode, $langcode);

  // The default ::buildMultiple() #pre_render callback won't run, because we
  // extract a child element of the default renderable array. Thus we must
  // assign an alternative #pre_render callback that applies the necessary
  // transformations and then still calls ::buildMultiple().
  $build = $build_list[0];
  $build['#pre_render'][] = [
    $this,
    'build',
  ];
  return $build;
