Description

In order to be allowed to use `import.meta.url` in my jest tests, I turned on the option `--experimental-vm-modules`. But thereby I cannot import jsdom-worker anymore.

I have the following stack trace:
```
FAIL src/anonymized-path/anonymized.test.tsx
● Test suite failed to run

Must use import to load ES Module: C:\anonymized-path\anonymized\node_modules\node-fetch\src\index.js

4 | import { enableFetchMocks } from 'jest-fetch-mock';
5 | import { readFileSync, readdirSync } from 'fs';
> 6 | import 'jsdom-worker';
| ^
7 | import { getPathFromPublic } from 'utils/helpers';

at Object. (node_modules/jsdom-worker/dist/jsdom-worker.js:1:89)
at Object. (src/setupTests.ts:6:1)
```

Would you have insight how to solve this issue?

```
$ node -v
v17.9.1
$ npm -v
8.11.0
```

Research direction

Start with the import in src/setupTests.ts and the failing entry point shown in node_modules/jsdom-worker/dist/jsdom-worker.js, then reproduce the failure using Node v17.9.1 with --experimental-vm-modules. Done means jsdom-worker can be imported under that configuration without the node-fetch ES module error and the test suite starts successfully.
