Zhonyas and Tahms Devour

It made me curious when I saw Tahm come out, but DOES ANYBODY KNOW if Tahms Devour (while carrying ALLY Champ) will stack with Zhonyas (when activated). Like Tahm and Ally Champ are in Zhonyas or will he spit out the ally? Or is this gonna be a bug that Riot will fix. Haven't done it so....
