Banning based on specified statuscode(s) X retries not working

[Weav3r]

Hi all. I've been testing out this plugin by using the docker-compose.yml in the repo. I basically cloned the repo and started the containers.
In the example docker-compose.yml, I expected the banning for the fail2ban-local.localhost route to be based on exceeding the retries for the specified status codes (below) but this doesn't seem to work for me.

...
traefik.http.middlewares.fail2ban-local.plugin.fail2ban-local.rules.maxretry: 4
...
traefik.http.middlewares.fail2ban-local.plugin.fail2ban-local.rules.statuscode: "400,401,403-499"
...

I know that this plugin supports banning based on status codes (ref. #108). However, I find the banning to be always based on the number of requests regardless of the status code(s) specified.

Not sure what's going on. Any help/clarification on this would be very appreciated.
