23630	AlterModelTable doesn't rename auto-created tables	no	nobody	"According to https://docs.djangoproject.com/en/dev/ref/models/fields/#ref-manytomany, when a m2m field uses an automatic (implicit) through model, the through model's table is named by combining the containing model's table-name and the field name. Consequently, if a model contains such m2m fields and its table name is changed by a migration, the m2m field's tables should also be renamed.

This doesn't happen (see comment:4 and comment:5 for details), leading to broken models.
