/**
* This hook is meant to be used inside the render function of `List` style components. It is used
* by `ListBox`. This hook gives list-based components their static and dynamic APIs to handle list
* items. This hook should only be used if you want to implement your own List. For example,
* `Tabs.List` uses this hook, but `Menu.List` uses `ListBox` which uses this hook.
*
* ```tsx
* const MyList = createContainer('ul')({
* modelHook: useListModel,
* })((elemProps, Element, model) => {
* return <Element {...elemProps}>{useListRenderItems(model, elemProps.children)}</Element>;
* });
```
