For anyone who wants to try debugging it:

scripts/make-rpc-testenv.sh
. venv/bin/activate
cd deltachat-rpc-client
RUST_LOG=iroh_net=trace,iroh_gossip=trace pytest tests/test_webxdc_iroh.py -s |& cat > 1.log
^C after some time because it never finishes
less -r 1.log

Replaced with #5602, I am sorting this into separate commits and removed custom subscriber which is stealing events.
