Sylas not only steal ults, it is taunts as well. Weird replay bug too

I just played an aram with Sylas where pressing CTRL + 2 to taunt(and only taunt, not laugh or anything), it was using champion taunts from the enemy team, for example both Annie and Diana's voice came out of Sylas in that one game and I was playing against them and FYI I didn't steal Annie ult a single time so I doubt it has anything to do with his ult

I don't know if this is intended, i hope it is because I don't see how it could even be a bug without someone deliberately placing it there which would be ridiculous but hey whatever wouldn't be the first time... _ _ _ EDIT: after trying to record proof through match history replay, one moment I heard the taunt bug and when I Rewind 15 secs to hear again and record, it swaps to normal Sylas taunt... Now I know this is some weird bug that is both game and replay related because this also happens when viewing 2 sides of creep block and PROVES that creep block IS bugged To prove that theres some weird '2 sides of things' going on, I AM NOT trying to refresh an old post, but if you care please compare the 2 gragas clips in this post, it's the same clip just Rewind 15 secs https://boards.na.leagueoflegends.com/en/c/general-discussion/mYIcFLeQ-creep-block

give me a job riot lol I'm like a glitch radar
