PermissionsMixin

I have the following models in my project. Running makemigration works,
but running migrate causes a CircularDependencyError.

{{{
#!python

from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin
from django.db import models

class Employee(AbstractBaseUser, PermissionsMixin):
USERNAME_FIELD = 'id'

class ModelA(models.Model):
person = models.ForeignKey(Employee, blank = True, null = True,
default = None)

}}}

I think this could be related to #22485 and/or #21968 but I'm not sure.
Test project attached.
