Actually, I think their behavior is just "DDL issues a COMMIT", so that
after that you are out of the transaction and the INSERT commits
immediately. Some experimentation shows that mysql doesn't issue a
warning for rollback-outside-a-transaction, so the lack of any complaint
at the rollback step is just standard mysql-ism.
Yes, their manual explains this and warns against it. The full list is
