Error: Invariant: attempted to hard navigate to the same URL

Link to the code that reproduces this issue

https://github.com/igorwessel/next14-canary-hard-navigate-issue

To Reproduce

1. Run the build command in the project: npm run build
2. Start the server with npm run start (Production)
3. Access the localhost:3000, and stay on the route "/"
4. Repeat steps 1 and 2 to simulate a new deployment
5. With the previous page still open with the old deployment, click on "Current Page". This will trigger the error.

Current vs. Expected behavior

I expected Next.js to perform a hard-refresh when it receives a 404 status code from the JSON of the dynamic route, similar to what happens when it navigates to another page. However, I observed that the error Error: Invariant: attempted to hard navigate to the same URL is thrown.

Additional context

Occurs in next@12.3.4 too

From our understanding of the previous issue, Next.js should perform a hard-refresh when it receives a 404 while trying to perform data-fetching on a dynamic page with some data-fetching method like getServerSideProps. Currently, this error occurs on the same page, but it does not happen if we go to another page.

If this is not a bug, how can we solve this problem/mitigate given that requests to .next/data/{buildId} are dynamic?
