Running Traefik 2.2.0. Need to define some CORS Header:

> apiVersion: [traefik.containo.us/v1alpha1](http://traefik.containo.us/v1alpha1)  
> kind: Middleware  
> metadata:  
> name: longhorn-cors  
> namespace: default  
> spec:  
> headers:  
> accessControlAllowMethods:  
> - "GET"  
> - "OPTIONS"  
> - "PUT"  
> accessControlAllowOriginList:  
> - "[http://localhost](http://localhost)"  
> accessControlMaxAge: 100  
> addVaryHeader: "true"

Dashboard does not show OriginList. Is this an UI-issue only? Or was OriginList not accepted for any reason?  
Thanks,
