Pubsub stop working after peer restart.

[AlexMesser]

I have two peers, both are connected to the same public wrtc server and subscribed to the same topic. When we run both peers at the same time, everything works as expected. But when we restart one of the peers, it does not see another peer in the list of topic subscribers after restart. I have created a reproduction repository for better explanation.

What I have tried:

• changing public wrtc server (/dns4/wrtc-star1.par.dwebops.pub/tcp/443/wss/p2p-webrtc-star) to my own wrtc server - the same issue
• avoid using wrtc and use relay server instead - same issue
• tested in local network - works as expected, peers sees each other after restart.

tested with floodsub - same issue. So, it seems issue is not in gossipsub, but in libp2p itself, closing.
