10237	Symmetry is lost when inheriting a self-referential m2m field	Justin Lilly	Justin Lilly	When extending a model (via MTI, not ABC), the implicit symmetrical=True reference wasn't being maintained because the current class was being checked against the parent (which weren't the same type). By changing this to an isinstance call instead of a !__class!__ comparison, it properly compares to parent objects.		closed	Database layer (models, ORM)	1.0		fixed	mti, m2m, inheritance		Accepted	1	0	0	0	0	0
