Next.js staleTimes behavior issue Demo

title: Once the Router Cache is used once, the value of staleTimes.dynamic is applied the next time.

To Reproduce

1. pnpm clean-start.
2. Access http://localhost:3000.
3. Click link to /static.
4. Your devtools network tab show that the request is not made.
5. Browser back to / soon(under 3 seconds).
6. Click link to /static again.
7. Your devtools network tab show that the request is made.

Current vs. Expected behavior

My staleTimes configuration is:

const nextConfig = {
  experimental: {
    staleTimes: {
      dynamic: 3,
      static: 10,
    },
  },
};

I expect that staleTimes.static is applied all times, but it is not applied after the first time.
