MultiList showLoadMore WITH nestedField

**Affected Projects**
React

**Library Version:** x.y.z
^4.0.0-rc.12

**Describe the bug**
When using the MultiList component in a React application with the nestedField and showLoadMore props, the component fails to render.

**Expected behavior**
The MultiList component should render correctly and display a "Load More" button to allow the user to load more items in the list.

**Steps to reproduce**

- Use the MultiList component in a React application.
- Set the nestedField prop to a nested field in the data source.
- Set the showLoadMore prop to true.
- Render the component.

**Additional information**
This issue seems to occur only when using both the nestedField and showLoadMore props together. When using either prop separately, the component renders correctly without any errors.

**To Reproduce**

```javascript
