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

[pillowfication]

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.

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 (
    <ListBox
      showSearch
      searchLimit={5}
      actions={[<IconButton key='filter' onClick={toggleFilter}><Filter /></IconButton>]}
      items={options
        .filter((_, index) => !filter || index < 3)
        .map(option => ({ name: option, value: option }))}
      onChange={() => {}}
    />
  )
}
