Reproducible test case

Nock Version

13.2.9

Node Version

19.1.0

TypeScript Version

No response

What happened?

When the linked example is run on Node.js 19.0.1 and earlier, it prints

Response headers: { 'x-ratelimit-remaining': '4999', 'content-type': 'application/json' }

When run on Node.js 19.1.0 it prints

Response headers: {}

which is missing the response headers given to nock.

Refs:

• v19.1.0: breaking change, http.IncomingMessage headers setter no-op nodejs/node#45510
• http: headers(Distinct), trailers(Distinct) setters to be no-op nodejs/node#45176

The breaking change is being reverted for 19.x but will be re-landed as semver-major for 20.x

This is working with version 20:

And v19.9.0.
