orphanRemoval some times doesn't work because it depends on (gets schedulled in) PersistencCollection. And we might be calling ArrayCollection#removeElement().

Following is a snippet of the PersistencCollection#remove()

    if ($this->association !== null &&
        $this->association['type'] & ClassMetadata::TO_MANY &&
        $this->owner &&
        $this->association['orphanRemoval']) {
        $this->em->getUnitOfWork()->scheduleOrphanRemoval($removed);
    }

and ArrayCollection does not do that.
