@mirjak  In general, QUIC doesn't process duplicate packets and QUIC doesn't ACK anything it can't process, so ignoring duplicate marked packets matches with this model.

I suspect a lot more marked packets will be dropped because they were undecryptable(ie: 0RTT) than because of duplication, since duplication is very rare in my experience, and when it does occur, it'd commonly be better to ignore the second mark anyway, since the marking would occur before the duplication.
