What steps will reproduce the bug?

• Checkout https://github.com/dgozman/node-loader-repro.
• Install Node.js v22.7.0.
• Run node main.js.

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

Always reproduces with v22.7.0, does not reproduce with v22.6.0.

Running as node --no-experimental-detect-module main.js does not trigger the assert, and instead shows an expected error message "SyntaxError: Cannot use import statement outside a module".

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

> node main.js
<...>/imported.ts:1
import fs from 'fs';
^^^^^^

What do you see instead?
