I just got into champ select with my team and we did chat, a lot.
Our chat log was longer than usual, but someone on the enemy team dodged.
So I got put back to queue and I noticed that chat was scrolled all the way up, to the beginning.
How to reproduce :
1.Join the champ select
3.Someone dodges, you get put back to queue
4.Look at the chat in the bottom left corner, its scrolled all the way up and now you have to scroll all the way down to read what your new team is talking about.
