Mattermost BUG with volume mounts in values.yaml

version 1.8.0 Adding the volume mounts for SSO OIDC integration to mattermost values does show up in the Helm cluster values but never gets applied to the pod. I had to manually add the cert to the pod and push it into my repo, then sso worked

  mattermost:
    values:
      volumes:
        - name: ca-cert
          secret:
            secretName: ca-secret
            defaultMode: 0644
      volumeMounts:
        - name: ca-cert
          mountPath: /etc/ssl/certs
          readOnly: true
          subPath: ca.crt
