Problem with multiple dash (--) in middleware annotation

Traefik Traefik v2 (latest)
1

I want to be able to add middlewares like this
traefik.ingress.kubernetes.io/router.middlewares: namespace-test--frontend-redirect@kubernetescrd
but this raises 404 not found.
when i change that to
traefik.ingress.kubernetes.io/router.middlewares:namespace-test-frontend-redirect@kubernetescrd
it works correctly (bot middlewares exists). I think there is a problem in using multiple dashes in middleware name.
traefik:2.7.1

Try Traefik latest v2.10
