(MAJOR) Illaoi dance spam causes major lag spikes and disrupts audio all over the map

When an Illaoi on either team spams her dance for an extended period of time, this resulting rumbling sound is heard. This sound compounds over time causing the game to not play audio effects for either team, and anywhere near the tentacles you're most likely to encounter lag spikes as seen in the video. This glitch could be game breaking as it causes both teams to lag, during a recent game me and 2 other friends had our fps's lowered to around 4-10 at times when I average about 300, one of us even got disconnected it was so bad. We then went to document this in a custom game, which is the youtube video linked.

EDIT: This glitch only occurs if the Illaoi moves right after starting the dance and continues to dance then more (etc)
