 // Maps [requesting_origin, embedder] to content settings.  Written on the UI
 // thread and read on any thread.  One instance per profile. This is based on
 // HostContentSettingsMap but differs significantly in two aspects:
 // - It maps [requesting_origin.GetOrigin(), embedder.GetOrigin()] => setting
 //   rather than host => setting.
 // - It manages only Geolocation.
