I understand the assumption, makes sense when not considering such weird
use cases as we might have in Selectrum ;) In Selectrum candidates are
shown vertically stacked, we additionally ensure that candidates are a
single line. It works pretty well and makes a lot of things easier to
deal with in our UI. Thanks for adding this!
