Automatically sending JSON in POST is not working as expected

Environment

ofetch v1.0.0
node v16.19.0

Reproduction

https://gist.github.com/marr/4243d2bd64f9c0abe8b1f135ae7c7eb6

I've created a simple repro using a mock postman server. You won't be able to see the logs with the URL that my repro case is creating. You can get basic "request logs" by creating a mock server in postman and sending a PATCH or POST request to it.

The Request Body in the mock server log is correctly a JSON object, only when the body is stringified in the request. I've not been able to reproduce in the ofetch tests yet.

Describe the bug

The incorrect behavior can be seen in the screenshot below.

Note the request was sent like: await ofetch(url, { body: { x: 1 }, method: "PATCH" });

The desired request body looks like this:

You can see the content-type and accept headers are set and the request body looks correct. This used a stringified version of the body in the request:
await ofetch(url, { body: JSON.stringify({ x: 1 }), method: "PATCH" });

This was an incorrect repro case. I was using a URL object as the first parameter, which caused the request to not be proccesed as expected. Maybe more of a feature request to be able to use URL objects with fetch calls.
