Fund: Fetching request from cache fails on certain websites

Describe the bug

Node.js version: 18.12.1
OS & version: Windows 10 @ 10.0.19044 Build 19044
Docker v4.14.0 on Redis v7.0.8

When sending a GET request to certain websites with caching enabled on got,

the first request will be successful, and the response is added to the cache.
subsequent requests are not successful, and instead causes node to freeze.

I noticed that this is not reproducible for all websites, but found that two websites, danbooru and tatsu, using Cloudflare that have their cf-cache-status set to DYNAMIC appear to consistently result in freezes after attempting subsequent requests.

Other websites that don't use CloudFlare, like GitHub on Varnish, or have cf-cache-status of HIT or REVALIDATED, like jsonplaceholder and oneskyapp, appear to be perfectly fine, with the response sent from cache.

Actual behavior

Send a GET request and saves response to cache.
A second request to something that is in cache will result in a freeze.

Expected behavior

Send a GET request and saves response to cache.
A second request should successfully return the cached response.

Code to reproduce

Start a Redis container using Docker -- https://hub.docker.com/_/redis
docker run --name some-redis -d -p 6379:6379 redis

See: https://github.com/Aericio/got-cache-issue

please look at the source code for extra comments.
yarn/npm install
yarn/npm run dev

You will notice that, on the first run of the code:

It will pass the first three tests.
It will run the first iteration of the fourth test, but hangs on the second iteration.
requesting is the final message, no still alive which should print after request has been completed.

What data is being logged?

{
    url: res.url,
    cache: res.isFromCache,
    "cf-cache-status": res.headers["cf-cache-status"], // cloudflare cache
    "x-cache": res.headers["x-cache"] // GitHub varnish cache

- A potential cause could be that `cf-cache-status` is `DYNAMIC` here, compared to `HIT` or `REVALIDATED`.
- On the fifth test, I found another website with `cf-cache-status: DYNAMIC` header.
- After commenting out the fourth test so that I could get to the fifth test, I was met with the same behavior.
- First request goes through when cache doesn't exist, but hangs after the request has been added to the cache.

This issue is also present when using new Map() as the cache.
