Can't stop podman container correctly in detached mode

[zhoreeq]

nostr-rs-relay container runs and stops on CTRL-C correctly in attached mode (as described in the README).

But it can't stop correctly when running in detached mode:

localhost:~$ podman run -it -d --rm --name nostr-relay nostr-rs-relay:latest
42ce2a4bd94da94cecbacae6e3e496f2c44f1ffa1b52fa2320517977700f4bce
localhost:~$ podman stop nostr-relay
WARN[0010] StopSignal SIGTERM failed to stop container nostr-relay in 10 seconds, resorting to SIGKILL

Debug log in detached mode (it doesn't show that it is catching any signals):
