[Bug]: Jest does not automatically mock AsyncGenerator functions

Version

27.3.1

Steps to reproduce

module/index.js

async function* asyncGenerator() {
    await new Promise(resolve => setTimeout(resolve, 100));
    yield 'done';
}

function* syncGenerator() {
    yield 'done';
}

module.exports.asyncGenerator = asyncGenerator;
module.exports.syncGenerator = syncGenerator;
module.exports.asyncMethod = async () => {
  return 1;
}
module.exports.syncMethod = () => {
  return 1;
}

index.spec.js

jest.mock('./module');
const mod = require('./module');
 
describe('all methods', () => {
  test('should be mocked automatically', () => {
    expect(mod.syncMethod).toBeDefined();
    expect(mod.asyncMethod).toBeDefined();
    expect(mod.syncGenerator).toBeDefined();
    expect(mod.asyncGenerator).toBeDefined(); // <-- this is where it fails
  });
});

Expected behavior

Jest should automatically mock AsyncGeneratorFunction functions as it also automatically mocks Function, AsyncFunction and GeneratorFunction.

Actual behavior

module.exports.asyncGenerator is undefined and not mocked at all. It needs to be explicitly defined and mocked.

Additional context

The issue #5979 described the same problem for synchronous generator functions. In the PR #5983 the support for GeneratorFunction was added. This could also be done for AsyncGeneratorFunction.

Can confirm this issue in 2022 for jest version 27.5.1
