Route rules are not applied if a route does not have a GET route

[MickL]

Environment

nitropack: 2.9.6

Reproduction

https://stackblitz.com/edit/github-xaqmuq?file=nitro.config.ts

Describe the bug

Setting cors: true to does not work:

routeRules: {
    '/**': {
      cors: true,
    },
},

The browser still throws cors error:

Access to fetch at 'http://localhost:3333/' from origin 'http://localhost:3001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

With header, too:

routeRules: {
    '/**': {
      cors: true,
      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Headers': '*',
      },
    },
  },

Error:

Access to fetch at 'http://localhost:3333/' from origin 'http://localhost:3001' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

Additional context

I already opened an issue at Nuxt that setting corse:true does not have an effect on /api routes, only on /public folder.

Logs

No response
