I cannot mock SketchPicker using jest

I'm trying to test a component of my own that makes use of Sketch Picker

```
import { SketchPicker } from 'react-color';

jest.mock('react-color');

describe('when color is changed on SketchPicker', () => {
beforeEach(() => {
SketchPicker.mockImplementation((props) => {
this._onChange = props.onChange;
return <>SketchPicker;
});
});

afterEach(() => {
SketchPicker.mockClear();
});

it('should trigger onChange', async () => {
const { getByTestId, debug } = await render();
fireEvent.click(getByTestId('color-picker-current-color'));
debug();
});
});
```


The error does not come up if I remove the mock implementation.

No repository file or project test is named. Start by reproducing the provided Jest test with the SketchPicker mock and compare it with the version without the mock; the issue needs a clearly identified error and expected behavior before completion can be defined.
