Crash at request-reponse assertion

[nazar-pc]

I have request-response protocol crashing on this debug assertion:

rust-libp2p/protocols/request-response/src/lib.rs

Line 656 in 0ceb658

debug_assert_eq!(connections.is_empty(), remaining_established == 0);

Logs with following level:

RUST_LOG=info,subspace_network=trace,libp2p_core=trace,libp2p_identify=trace,libp2p_swarm=trace,libp2p_kad=trace,libp2p_autonat=trace,libp2p_request_response=trace

UPD: While reproducible, the same app with RUST_LOG=trace:

Could this be related to #4773?

Do you use any connection management behaviours like connection limits? If yes, then the temporary fix is to put them as the very first field in your behaviour struct.

Possibly related, we do use connection limits indeed. Will move connection limits to the beginning then and closing this as duplicate.
