while stale option desn't work?

[mblandr]

Here is the repo
https://github.com/[mblandr/next-stale-test](https://github.com/mblandr/next-stale-test)
Why in production in every client-side navigation I see that rscp for / and /about download every time.
But I have stale setting 10s? No matter, canary/stable version, inclulde experimental.staleTimes or not.
What do I miss?
