`superfluous response.WriteHeader call` when `SecRuleEngine On`

[Forza-tng]

When I enable Coraza on a host, I get these lines repeating in my main caddy log.

{"level":"info","ts":1778924053.9293013,"msg":"http: superfluous response.WriteHeader call"}
{"level":"info","ts":1778924055.384399,"msg":"http: superfluous response.WriteHeader call"}
{"level":"info","ts":1778924056.2240324,"msg":"http: superfluous response.WriteHeader call"}
{"level":"info","ts":1778924058.6971262,"msg":"http: superfluous response.WriteHeader call"}
{"level":"info","ts":1778924059.9666855,"msg":"http: superfluous response.WriteHeader call"}
{"level":"info","ts":1778924061.1894848,"msg":"http: superfluous response.WriteHeader call"}

A typical caddy vhost looks like this:

(main) {
	tls /etc/caddy/certs/{args[0]}_fullchain.pem /etc/caddy/certs/{args[0]}_privkey.pem {
		curves x25519mlkem768 x25519 secp521r1 secp384r1 secp256r1
	}
	log {
		output file /var/log/caddy/{args[0]}.log {
			roll_disabled
		}
		format json
	}
	encode zstd br gzip
}
