Reproduction steps

I opened https://github.com/mswjs/interceptors/pull/745 that makes the tests in the reproduction repo all pass when I use it in place of the upstream.

To do this I added an override for pnpm to use my local copy of the interceptors package:

    "pnpm": {
      "overrides": {
      "@mswjs/interceptors": "file:/path/to/local/projects/juicemia/mswjs-interceptors"
    }

I then built the interceptors package using pnpm build and installed it in the reproduction repo by removing node_modules and running pnpm i again.
