Use Reference Number in Internal Lookup?

Previously, in typeahead fields you were able to type in the object reference number, but it looks like this is not a functionality of the internal lookup field? Does anyone know if this is a future-state functionality?

Example: Reference # 172401 pulled up the project named “25-26 Training Task Queue” for the Project typeahead. When I type that same number into the internal lookup field it returns “No results”.
