Describe the bug

When using ofetch.raw the raw response object cannot be parsed with json method (this works well with ofetch.native) . The failure happends both on client and server side thus I think it's not related to Node.

Additional context

I'm using @iconify/vue library. It provides setFetch method to use a custom fetch API. I have set fetch.raw in order benefit from the interceptors feature. The response on fetching icons is JSON thus it is parsed with json method.
