[v4] Content is upside-down after build while fine in dev

[nathanclevenger]

Describe the bug

When in dev mode, everything looks and works fine. After build & start, either locally or on Vercel, the content is displayed upside down.

You can view it upside down at https://mdxld.org

To Reproduce:

With this repo: https://github.com/ai-primitives/mdxld.org

1. Run pnpm dev
2. Observe that everything looks fine
3. Run pnpm build
4. Run pnpm start
5. Observe that the content is upside down

Expected behavior

I would expect build and dev to behave the same, and the content to be right-side up

I had the same issue of the page getting displayed upside-down. My next version was "next": "^14.2.5". I updated the package.josn to "next": "^15.1.4" and ran npm i next and issue is now fixed.
