This is long-standing behavior, I'm afraid.

FileField docs:

Note that when a model is deleted, related files are not deleted. If you need to cleanup orphaned files, you’ll need to handle it yourself (for instance, with a custom management command that can be run manually or scheduled to run periodically via e.g. cron).

Just quickly trying to think about how one might tie the transaction rollback into the file upload handling, a periodic cleanup command is instantly more appealing. I hope that makes sense.
