happy to report that is is working fine on 9.4.4 - but after seeing if I could reproduce on a next.js/examples paired down repo with the latest canary next.js - it was reproducible. (this could be a functionality changing that I haven't caught in the docs) - but it feels like a bug to me

Fixed via https://github.com/vercel/vercel/pull/4778 (soon to be released)
