[nextjs app router] `ClerkProvider` breaks 404 routing about javascript

Please note that this does not occur when running in development. You'll need to build and start the server in order to reproduce this.

For the visual learners out there...

I also got an error deploying on vercel Nextjs 14 but everything was perfect during development.

@kaksv yes, this only seems to occur during while running in dev mode. Notably, this is reproducible locally though by building and serving locally.

There's a worse version of this bug that occurs too. It seems that only navigating to the root page breaks, so there's scenarios like:

1. Navigate to "/fake-page" -> 404 non-found.tsx renders
2. Navigate from there to "/real-page" -> /real-page/page.tsx renders
3. Navigate from there to "/" -> No navigate!

This is really bad! In practice, a 404 page being buggy is much more acceptable than a 404 page breaking a completely unrelated page
