Version	2.19.5

Summary

Hi Doctrine team,

When upgrading from doctrine/orm 2.19.4 to 2.19.5, a behavior changed when retrieving an entity scheduled for deletion from the database before the actual flush.

Before 2.19.5, the entity scheduled for deletion and the entity retrieved from the database were 2 different objects with the previous state in the last one, which allowed us to know what was in the entity (e.g. the parent relation in my case), now it seems to be the same object.

It seems related to this PR : #11428. If I revert the changes locally, i got back the previous behavior.

Previous behavior

Current behavior

How to reproduce

#[AsDoctrineListener(event: Events::onFlush)]
class DummyListener
{
    public function onFlush(OnFlushEventArgs $eventArgs): void
    {
        $objectManager = $eventArgs->getObjectManager();
        $uow = $objectManager->getUnitOfWork();

        foreach ($uow->getScheduledEntityDeletions() as $entity) {
                $originalEntity = $objectManager->getRepository($entity::class)->find($entity->getId());
                dump(['Saved Entity' => $entity]);
                dump(['Original Entity' => $originalEntity]);
        }
    }

Same result if using $uow->getOriginalEntityData($entity) instead of direct call to the database to retrieve original data.

I've seen the issue #11448, but i don't think that's exactly the same problem.

Any toughts ?

Friendly ping @xificurk

I still got the same result by upgrading to v3 and I can't find a way around the problem.

FI, $uow->getOriginalEntityData($entity) give also the same reference
