Zhonya's During Galio Ult [CLIENT]

If you Zhonya's ~1-2 seconds into Galio ult, you can go into stasis, but Galio's ultimate is a taunt:

A unit that is taunted will attempt to attack the source for the duration, during which time they cannot control their own movement or attacks, and cannot cast abilities, activate item or use the summoner spells Flash and Teleport. (http://leagueoflegends.wikia.com/wiki/Taunt#Taunt)
