Rewrites are in conflict with i18n

To Reproduce

{
  source: "/:path((?!api/).*)",
  has: [
    {
      type: "host",
      value: "localhost",
    },
  ],
  destination: `/test.com/:path*`,
}

Without i18n config, the rewrites config works very well. But with i18n config, the homepage localhost:3000 goes to 404, I have to add extra rewrite rule:

{
  source: "/",
  has: [
    {
      type: "host",
      value: "localhost",
    },
  ],
  destination: `/test.com`,
}

to make the homepage work as expected.

Current vs. Expected behavior

I18n config should not affect rewrites config, isn't it?

@yunsii Thank you for submitting an issue!

Curious, does it work with beforeFiles instead?

All requests return 404 if I change afterFiles to beforeFiles directly 😦
