Code

protected function initFormLangcodes(FormStateInterface $form_state) {
    // Store the entity default language to allow checking whether the form is
    // dealing with the original entity or a translation.
    if (!$form_state->has('entity_default_langcode')) {
        $form_state->set('entity_default_langcode', $this->entity
            ->getUntranslated()
            ->language()
            ->getId());
    }
    // This value might have been explicitly populated to work with a particular
    // entity translation. If not we fall back to the most proper language based
    // on contextual information.
    if (!$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.
        $form_state->set('langcode', $this->entityRepository
            ->getTranslationFromContext($this->entity)
            ->language()
