This is the place where UnitOfWork continues (in loop) with child entity with relation OneToMany and deletes parent before child.

I have this in User entity:

and this in Gallery entity:

Apparently, Gallery does not have className as User and it's deletion is not executed before user.
But, in UnitOfWork::$entityDeletions gallery comes first and user second. Because of foreign key gallery should be deleted first, then user.

Is this a bug or have I done something wrong?

More info on entityDeletions property:

and part where it checking whether className is equal with entity className
