    // 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')) {

        // 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.
