Jest mocking module in external file outside of test doesn't work - mocking lodash debounce

Question

I'm trying to export a mocked module - lodash debounce specifically - in a testUtils file to mock a module, but it isn't working. It only works if I mock the module in the individual test file. Trying to get DRY code via utils file.

Using "@testing-library/jest-dom": "^5.11.6",

This an extension question of the accepted answer in issue How can I mock an ES6 module import using Jest?

This doesn't work - tests fail:

    // 'lodashUtils.ts
    export { default as debounce } from 'lodash/debounce';
    
    // testUtils.ts
    const mockLodashDebounce = () => {
        jest.mock('common/utils/lodashUtils', () => ({
            ...jest.requireActual('common/utils/lodashUtils'),
            debounce: jest.fn((fn: any) => {
                fn.cancel = jest.fn();
                fn.flush = jest.fn();
                return fn as ((...args: any[]) => any) & any;
            }),
        }));
    }
    
    // myTest.test.ts
    import {mockLodashDebounce} from './testUtils';
    
    mockLodashDebounce();

This works - tests pass: (but must do this in each test for components using debounce)

    // myTest.test.ts
    ...
    jest.mock('common/utils/lodashUtils', () => ({
        ...jest.requireActual('common/utils/lodashUtils'),
        debounce: jest.fn((fn: any) => {
            fn.cancel = jest.fn();
            fn.flush = jest.fn();
            return fn as ((...args: any[]) => any) & any;
        }),
    }));
    
    ...
