jsdom: ReferenceError: AggregateError is not defined

Basic info:

• Node.js version: 14.15.5
• jsdom version: 16.6.0

Minimal reproduction case

I recently upgraded jest-environment-jsdom from 26.6.2 to 27.0.3 and I’m now seeing some issues that I believe are related to this package. If I run multiple test files at once, everything is fine, but if I run a single test file, then there’s a crash in this package:

  ● Test suite failed to run

    evalmachine.<anonymous>:1
    AggregateError
    ^

    ReferenceError: AggregateError is not defined

      at evalmachine.<anonymous>:1:1
      at setupWindow (node_modules/jsdom/lib/jsdom/browser/Window.js:111:55)
      at new Window (node_modules/jsdom/lib/jsdom/browser/Window.js:223:3)
      at exports.createWindow (node_modules/jsdom/lib/jsdom/browser/Window.js:95:10)
      at new JSDOM (node_modules/jsdom/lib/api.js:36:20)

I’m not sure what’s going wrong here. I’ve never seen this error before and I can’t find any trace of it on the Internet, but after upgrading, everyone on my team is seeing this problem.

I had initially filed this issue here (https://github.com/simon360/jest-environment-jsdom-global/issues/47), but even after purging jest-environment-jsdom-global from the repo, I’m still hitting this crash.
