In Symfony 4.4.17 (I think), using ManyToMany in doctrine, along with indexBy="person_id" (in the related entity, which has a property of "id" (which in-turn uses the db column "person_id" worked as expected. When upgrading to Symfony 5.2.1, this stops working.

This change continues on from issue #37982 to fix a further edge case.
