Poro Toss is triggering Arcane Comet

Question about something that I'm not sure is a bug or intentional. I've been playing a few games of Legend of the Poro King yesterday and noticed that Arcane Comet is triggered by Poro Toss. I thought this was a bit weird, since Poro Toss is a summoner spell and those aren't supposed to trigger Arcane Comet (e.g. Ignite doesn't). So is this an oversight that will be fixed, or does the added tension of having to dodge both poros AND meteorites make the game mode that more exciting?
