Yasuo windwall is bugged for several patches

I was playing Thresh and i went to help my Mid player but I saw something strange. Yasuo windwalled my hook but the hook went through his windwall and CC him. I think this bugged must be fixed because is kind of game breaking to be honest. I hope Riot will fix this ASAP because it afects gameplay! I put the video link of what happed here if you want to watch!
