Gravitational Waves in Positively Curved Universe?

TL;DR

Would gravitational waves travel like light in a positively curved universe?

Hello everyone! I was listening to a podcast that featured a cosmologist and she mentioned that if the universe was positively curved (and therefore a sphere overall), light would travel around the universe and then end up where it started. I wondered, would a gravitational wave do the same?
