[Bug]: Wrong line numbers in reports with type: module in package.json and Node.js 24.12.0

[dword-design]

Version

1.57.0

Steps to reproduce

1. Clone https://github.com/dword-design/demo-playwright-tests-wrong-line-numbers
2. Have Node.js 24.12.0 installed and active
3. npm ci
4. npx playwright test

import { test } from '@playwright/test';

test('test', () => {});

Expected behavior

Running 1 test using 1 worker

 ✓ 1 tests/example.spec.ts:3:1 › test (1ms)

 1 passed (396ms)

Actual behavior

Running 1 test using 1 worker

 ✓ 1 tests/example.spec.ts:2:1 › test (1ms)

 1 passed (396ms)

Additional context

• I think it's related to fix(test runner): prevent esm loader deadlock #36187 where the source map loading was unblocked, but I guess the source maps are not there when the tests are loaded
• It works when type: module is removed from package.json
• It works in other Node.js versions, it only doesn't work with 24.12.0
• I also somehow got it to work with PLAYWRIGHT_WAIT_FOR_SOURCE_MAPS but it also lead to infinite loading issues (which probably is why the behavior has been changed)

I can reproduce it. Likely culprit is nodejs/node#60380

I'll keep it open to catch upvotes, we might want to issue 1.57.1 over it.

@pavelfeldman Ok thanks already!
