http response writeable stream not ending when used in pipeline (node >= 11.1.0)

[kevinmstephens]

We are seeing an issue with MITM involving:

• HTTPS requests (does not impact HTTP)
• Starting in Node 11.1 and continuing to current Node 14 (11.0.0 and prior works fine)

When we use the http response writeable stream provided by MITM in the nodejs internal streams pipeline method the pipeline callback is never invoked.

We have created a repo with an implementation and tests showing the problem. If you run yarn test with node v11.0.0 the tests will pass, if you run with v11.1.1 they will timeout.

The callback not invoked that should be is here: https://github.com/FormidableLabs/mitm-experiments/blob/main/index.js#L126

Thanks for your help!
