After double squashing migrate command fails with InconsistentMigrationHistory

[Jacob Walls]

[main/6.0]
Make four migrations, migrate, squash the first two, then squash the first three: then migrate (or makemigrations --check) fails.

manage.py makemigrations myapp --empty
manage.py makemigrations myapp --empty
manage.py makemigrations myapp --empty
manage.py makemigrations myapp --empty
manage.py migrate
manage.py squashmigrations myapp 0001 0002
manage.py squashmigrations myapp 0001_initial_squashed 0003
manage.py migrate

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration myapp.0004_auto_20250126_1339 is applied before its dependency new.0001_initial_squashed_0002_auto_20250126_1339_squashed_0003_auto_20250126_1339 on database 'default'.

Other migration commands can be subbed for that last call and still produce the same error, e.g. makemigrations --check, which is likely in a CI setting.
