Error when inserting in batch with joined table inheritance #1867
Description
A test is available here: DavideD@10ab8cd
The test only fails when batching is enabled.
The problem is in the way we have implemented ReactiveMutationExecutorStandard#performReactiveBatchedOperations.
It shouldn't delegate to the super reactive class, it should instead implement the batching and mimic what's happening in MutationExecutorStandard#performBatchOperations
The test passes without batching.
I will look into this after the upgrade to ORM 6.5.
