Why time-related operations of rxjs marbles testing does not work in Jest with ESM?

Question

I found that rxjs marbles tests failed on jest esm when using time-related(e,g. delay) operators. Check the test case here: https://github.com/jaohaohsuan/jest-preset-angular/commit/259b2361d37609e8a409bce96c953603739ef1cb

Does anyone have this issue?

I am using the example-app-v14 sample project as the test environment. yarn run test was passed, but yarn run test-esm didn't.

The moduleNameMapper of jest-esm.config.mjs file:

moduleNameMapper: {
    tslib: 'tslib/tslib.es6.js',
    "^rxjs(/operators)?$": '<rootDir>/node_modules/rxjs/dist/bundles/rxjs.umd.js',
    "^rxjs/testing":
      "<rootDir>node_modules/rxjs/dist/cjs/testing/index.js",
  },

The Jest test results:

 FAIL  src/app/issues/rxjs-marbles.spec.ts
  Rxjs marbles
    ✕ generates the stream correctly with delay 2s (12 ms)
    ✓ generates the stream correctly without delay (1 ms)

  ● Rxjs marbles › generates the stream correctly with delay 2s
