This condition removal (#2225) that was released in Altair was reverted in all clients after observing additional load due to the gossip amplification factor.
This condition halts duplicates from getting far in the gossip, but then these duplicates are still picked up in gossipsub's IWANT/IHAVE. This means that messages still eventually make it across the network but do not suffer the gossip amplification factor.
