Unable to reset entity manager with doctrine_integration enabled

[Jontsa]

Doctrine provides method to reset (create new instance of) entity manager. This is useful for example when entity manager has closed after failed transaction. Method is found Doctrine\Common\Persistence\AbstractManagerRegistry::resetManager(). Since doctrine/doctrine-bundle >= 1.6.4, the entity manager service is marked as lazy

But with JMSDiExtraBundle and doctrine_integration enabled, the entity manager is not reset and instead the old closed instance of entity manager is returned.

Downgrading to doctrine-bundle 1.6.3 fixes the issue.
Disabling JMSDiExtraBundle fixes the issue
Setting doctrine_integration: false fixes the issue

Tested using JMSDiExtraBundle 1.8.2, Symfony 3.3.9 and doctrine-bundle 1.6.8

I've also just spent a while debugging this. Before I thought about disabling the integration, I found that if I set 'doctrine.orm.default_entity_manager.delegate' to null in the container, subsequent calls to doctrine->getManager() return a correctly reset EM within the JMS proxy.

If the delegate were to be reset along with the em, I think this problem would go away. Not sure that's the correct approach however.
Symfony\Bridge\Doctrine\ManagerRegistry

If only my googling had found this one 3 hours ago.

Doctrine Bundle: 1.6.4
JMS DI Extra Bundle: 1.8.2
Symfony 2.8.27
