Participant Status Id mapping in Event Participant Export Doesn't Recognize Integers

One of the required fields for Participant import is "Participant Status Id" however "Id" number doesn't work. Only the text name of the Participant Status ("Registered", "Cancelled", etc) works. I don't know if this is a simple typo (remove the "Id" and the behavior makes sense) or if this is an indication that a class is not functioning properly.
