`ListBox` doesn't properly restore the search box input

When using the `showSearch` and `searchLimit` properties, the search input will clear itself despite the filter still being applied.

1. Create a `ListBox` with `showSearch={true}` and `searchLimit={10}`, and with more than 10 options.
2. Input some filter text into the search area.
3. Filter the options externally so that there are fewer than 10 options, and the search area is hidden.
4. Undo the filter to restore the search area.
5. The search filter is still applied, but the search input is blank.

```jsx
const options = ['One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten']

const MyComponent = (): JSX.Element => {
const [filter, setFilter] = useState(false)
const toggleFilter = (): void => { setFilter(!filter) }

return (
]}
items={options
.filter((_, index) => !filter || index < 3)
.map(option => ({ name: option, value: option }))}
onChange={() => {}}
/>
)
}
```
