How to retrieve subsidiary ID from Location record with search.LookupFields?

I am unable to retrieve the subsidiary id from the Location record. It only returns the subsidiary Name. I have tried with lookup and a search. The subsidiary appears to be a select field, but it is displayed as inline text. But for select fields it should return both value and text. In this case it only returns text. Is this a bug or expected?

If it is expected, is there a workaround with search? Only workaround I have found currently is to load the record and use getValue.

Code snippet:

const lookup = search.LookupFields({
    type: search.Type.LOCATION,
    id: '3',
    columns: 'subsidiary'
});
