console.log()'ging a response throws

[dferber90]

Logging a response throws, eg console.log(new Response("yes")) throws an error.

Reproduction

First way to reproduce (longer)

1. Create an Edge API Route
2. Fetch anything
3. Log the response

import type { NextRequest } from "next/server";

export const config = {
  runtime: "experimental-edge",
};

export default async function handler(req: NextRequest) {
  await fetch("https://example.com").then((res) => {
    console.log(res); // this throws, commenting out this line makes it work
    return res.text();
  });

  return new Response("yea");
}

Second way to reproduce (shorter)

import type { NextRequest } from "next/server";

export const config = {
  runtime: "experimental-edge",
};

export default async function handler(req: NextRequest) {
  const response = new Response("yea");
  console.log(response); // this throws, commenting out this line makes it work
  return response;
}

Error

Both of these throw

error - Error [TypeError]: Cannot delete property 'Symbol(set-cookie)' of #<HeadersList2>

I believe it's this line which ends up throwing https://github.com/vercel/edge-runtime/blob/e89ddce0566537e64c282229b0a2df63ea0dbe6d/packages/format/src/index.ts#L103
