Since release v2.16 this line of code won't save the entities in order of the loop anymore:

 foreach ($importDossier->getKlanten() as $klant) {
          $klant->setIsActive(true);
          $this->entityManager->persist($klant);
}

The last line to be executed will get an earlier id in the DB than the first iteration of the loop...which seems weird. Is this expected behaviour?

I noticed work was done on the commit order here: #10547
