Migration ignores Inheritance for Meta.default_permissions

[Ronny Vedrilla]

Hi there!

I just encountered a bug I believe. I created a [demo repo](​https://github.com/GitRon/django-migrations-bug-default-permissions-demo) to help isolate the problem.

I created two models here: ​https://github.com/GitRon/django-migrations-bug-default-permissions-demo/blob/main/migration_bug_demo/demo/models.py

Model one inherits from a Mixin which defines "Meta.default_permissions". The other one defines the Meta itself.

As you can see in the migration, the inheritance is being ignored:

Model with direct definition of "default_permissions":
​https://github.com/GitRon/django-migrations-bug-default-permissions-demo/blob/main/migration_bug_demo/demo/migrations/0001_initial.py#L29

Model with inherited definition of "default_permissions":
​https://github.com/GitRon/django-migrations-bug-default-permissions-demo/blob/main/migration_bug_demo/demo/migrations/0001_initial.py#L46

I hope you agree with my opinion! Other options like "managed" will be inherited, so I really do think this is a bug and not a feature.

Best regards
Ronny

As far as I'm aware, it's a duplicate of #29386.
