Helm's server-snippet not applied to config file

[ngocketit]

For fixing HTTP -> HTTPS redirect loop, I used this to install the controller with Helm:

controller:
  metrics:
    enabled: "true"
  config:
    ssl-redirect: "false"
    server-snippet: |
      listen 8000;
      if ( $server_port = 80 ) {
         return 308 https://$host$request_uri;
      }
  containerPort:
    http: 80
    https: 443
    special: 8000
  service:
    targetPorts:
      http: http
      https: special
    annotations:
      service.beta.kubernetes.io/aws-load-balancer-ssl-cert: "arn"
      service.beta.kubernetes.io/aws-load-balancer-backend-protocol: "http"
      service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "https"
      service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: "60"
      service.beta.kubernetes.io/aws-load-balancer-type: "nlb"

However, the snippet is not applied to /etc/nginx/nginx.conf file. The configmap is generated by Helm like so:

---
# Source: ingress-nginx/templates/controller-configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    helm.sh/chart: ingress-nginx-3.22.0
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/version: "0.43.0"
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/component: controller
  name: ingress-nginx-controller
data:

  server-snippet: "listen 8000;\nif ( $server_port = 80 ) {\n   return 308 https://$host$request_uri;\n}\n"

  ssl-redirect: "false"

If I put the snippet in Ingress, it works.
