This is not true. You must DKIM sign your DSN. As long as one
authentication mechanism passes and is aligned then DMARC passes.

>From your example, DKIM pass and is aligned, therefore DMARC should have
passed.

I feel you found a bug in the DMARC library of the recipient.

For info, we are aware of the SPF case re DSN and DMARC, and this will be
addressed.
