Change in 12.2.8 -- AP Credits No Longer Interfaced to AR as Stand-Alone CM's

I am working with a client who just upgraded to 12.2.11. Prior to upgrading, an AP credit memo against an invoice charged to a contract project that was already billed to the customer would be pushed over to Projects as a negative amount, and after completing the revenue and invoicing processes, the interface to AR and AutoInvoice would bring the negative amount into AR as a stand-alone credit memo that could then be applied to any open invoice on the customer's account.

According to note 2879366.1, it appears that this functionality was changed in 12.2.8 and now these AP credits will still be created in AR as credit memos, but the AutoInvoice process automatically applies them to the original AR invoice. If the customer has already paid that invoice, the transaction in AR shows a negative amount due. The note I found stated that creating these amounts as stand-alone AR credits would be an enhancement request.
