🐛 Bug Report
After upgrading Node.js 15.8 → 15.9 jest@next stopped supporting ESM.
I created an issue in Node.js repo as well nodejs/node#37426
To Reproduce
echo '{ "private": true, "type": "module" }' > package.json
yarn add nanoevents
echo "import { createNanoEvents } from 'nanoevents'" > index.js
echo "import './index.js'; it.todo('test')" > index.test.js
