Twitch browser bug

So whenever I get on twitch and type in a chat, the twitch website keybinds would be occurring when I type in the chat. For example if I type “Why you so mad”, it would pause the twitch stream 3x and mute it once. (space bar is to pause a stream, m is to mute). And also when I put it in theater mode it looks likes this: Processing: image.png… instead of normal theater mode (where the twitch stream would completely cover everything to the left of the chat). How can I fix this? I see my other friends that also use brave stream their screens on discord and they don’t have this issue.
