Before the previous commit, the client would not have been able to re-create the subflow that was previously rejected. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
