What steps will reproduce the bug?

const jsdom = new JSDOM('<!doctype html><html><body></body></html>');

How often does it reproduce? Is there a required condition?

Error is consistent. Was introduced in v19.7.0. Not reproducible on v19.6.1 and below.

What is the expected behavior? Why is that the expected behavior?

Should work same as in v19.6.1 and before. No error.

Do you have a test case using only the vm module? Your bug report is unlikely to get attention if it depends on a big third-party module like jsdom.

Since I'm not familiar with the inner workings of jsdom I cannot remove that as a dependency. All I can do is provide simple exact repro steps:

  • Save below snippet as test.js.
  • Run npm i jest jest-environment-jsdom
  • Run npx jest
/**
 * @jest-environment jsdom
 */
"use strict"
global.window = {};

Since the issue is reproducible with the snippet above on node version 19.7.0 but not on 19.6.1 I think there have been a breaking change somewhere between these two versions in node.

Works fine with latest nightly.
I also tested with a nightly before the mentioned commit (from March 17) and there it's failing. But on v20.0.0-nightly20230405f6f3e22016 it's passed.
Awesome, thank you very much.
I'm closing the ticket.
