Summoner Icon Emote Back?

recently just played a game as Nami support followed by Rakan support, a while ago I managed to get the summoner icon of the poro eating a poro snack (adorable). when I went to emote my mastery (ctrl+6) I instead got the old poro appear above my champion doing the cute squeal instead of the mastery emote. Is this a bug? or did it come back for a while without me realising? If so please keep it, I love it and it was a great surprise!
