  if (!$form_state
    ->has('entity_default_langcode')) {
    $form_state
      ->set('entity_default_langcode', $this->entity
      ->getUntranslated()

  }

  // This value might have been explicitly populated to work with a particular
  // entity translation. If not we fall back to the most proper language based
  // on contextual information.
  if (!$form_state
    ->has('langcode')) {

    // Imply a 'view' operation to ensure users edit entities in the same
    // language they are displayed. This allows to keep contextual editing
    // working also for multilingual entities.

      ->set('langcode', $this->entityRepository
      ->getTranslationFromContext($this->entity)
      ->language()
