Oracle Data Pump Schema Export and Public Synonyms

While testing a migration, I figured out that schema export using Data Pump doesn’t capture public synonyms on the objects in this schema. Does anyone know how to make Data Pump include public synonyms with schema export? Update: This is actually the same behavior as old Export utility.
