Link to the code that reproduces this issue
https://github.com/magicspon/next-link-test
To Reproduce
Build and deploy the app to vercel.
Go to the URL
Click on the "Broken link" button.
Observe, the 404 page is not shown.
This only happens when running on vercel, it's fine on localhost.
It also only happens when there is middleware on the site, even though these urls aren't matched by the middleware
Current vs. Expected behavior
When clicking on a link that 404's, I would expect to see the 404 page.
