32724	Deleting a MTI Child model will leave associated rows in the parent table.	Matthias Dellweg	nobody	"Steps to reproduce: 
1. Create a Parent and a Child model
2. Migrate and populate some rows in the Child table
3. Delete the Child table, create migrations and migrate
4. Observe that the Parent table is not empty

In contrast to that, if you remove rows from the Child table (while existing), the corresponding rows in the Parent table are deleted too.

This bug happens both on forward as well as reversed migrations.
