App Platform: how to make routes add prefix back in case of 301 redirects?

I have an App Spec containing a forwarding rule that looks like this:

ingress:
  rules:
    - component: {name: "api-container"}
      match: {path: {prefix: "/api/v1"}}

This enables “path trimming” (which I like!), so if I navigate to /api/v1/foo the container will only see /foo. Now if my app returns a redirect to /bar, it will not be rewritten to /api/v1/bar, which breaks the abstraction of “path trimming”.

Is there a way to enable this?
