   * Reacts to the PRE_ROW_DELETE event.
   *
   * For commerce_order rollbacks we want to preserve the order items and
   * prevent the 'usual' commerce behavior of deleting all order items
   * belonging to an order when deleting that order. That is done by
   * removing all order items from the order and saving the order.
   *
   * The extra steps to remove the order items from the order may significantly
   * increase the time to perform a rollback. To mitigate this it is best to use
   * drush and limit the number of records migrated during development. This can
   * be done with the 'limit' option or the 'idlist' option, as shown in the
   * following examples.
   * @code
   * drush migrate-import --limit=5 some_migration
   * drush migrate-import --idlist=42 some_migration
   * @endcode
   *
   * It is also possible to disable this feature and use a custom event
   * subscriber. Instructions on how to do that is in the Symfony documentation.
   *
   * @see https://symfony.com/doc/current/components/event_dispatcher.html#stopping-event-flow-propagation
   *
   * @param \Drupal\migrate\Event\MigrateRowDeleteEvent $event
   *   The event.
   *
   * @throws \Drupal\Core\Entity\EntityStorageException
