It doesn't appear we've made any changes to this recently - so its likely that this has been broken for awhile, and unfortunately our small but mighty team is tied up and likely wouldn't be able to resolve this immediately. I've created a bug ticket for it but I don't have an ETA.
In some cases, its possible that this component will show up in the search, but was not actually built out in React. I would refer to the React library directly and use the filtering options to see which components are actually available. Apologies for the issues here.
