Inconsistant completion of recurring contributions using trxn_id

If a payproc returns a trxn_id for a recurring contribution, two different outcomes happen based on whether a membership is involved. If it is a recurring contribution for a membership, the contribution status will be Completed, while a regular recurring contribution will be in a Pending state, requiring a webhook to complete it.

When payment_status_id =1 is also returned, the regular non-membership recurring contribution is set to Completed, as expected. It seems odd that trxn_id works to complete a recurring contribution sometimes. Since payment_status_id is the favored method, maybe returning trxn_id alone shouldn't complete any recurring contribution.
