Offering ping service on the same entrypoint as the api/dashboard?

I can't seem to be able to achieve this.
It's not clear from the doc whether it should be working or not.

Using a docker-compose.yml, the config I tested is:

command:
[...]
  - --ping=true
  - --ping.manualrouting=true
[...]
labels:
  - "traefik.enable=true"
  - "traefik.http.routers.traefik.rule=Host(`traefik.mydomain.org`)"
  - "traefik.http.routers.ping.rule=Host(`traefik.mydomain.org`) && Path(`/ping`)"
  - "traefik.http.routers.traefik.service=api@internal"
  - "traefik.http.routers.traefik.tls.certresolver=le"
  - "traefik.http.routers.traefik.entrypoints=websecure"
  - "traefik.http.routers.ping.service=ping@internal"
  - "traefik.http.routers.ping.tls.certresolver=le"
  - "traefik.http.routers.ping.entrypoints=websecure"

But I always get a 404 when trying https://traefik.mydomain.org/ping (where /dashboard works fine of course)

I'm still bumping my head against this.
Why is this not working?
