[Bug]: mouse hover generates too much traffic

[allevo]

Summary

When the mouse hovers on something, a download is performed. The cache is not used at all (max-age=0 with must-revalidate). This increase the network usage a lot.

Hello @allevo!
I can no longer reproduce this issue (Mozilla's Firefox). Can you check on your side or specify which browser you see this on (if)?
Scratch that, I see this happening when running the docs on the site, not locally.

I can reproduce it with Chrome, Safari, and Arc browser.

Exactly, this will be reproducible with any browser, as this seems to be default behavior of Next.js and the prefetching behavior that can't be simply disabled for hover: https://nextjs.org/docs/pages/api-reference/components/link#prefetch
