This bug appears when you hit the F6 key, which per default starts a twitch stream. If you do not own a twitch account, you recieve an error message.

What I expected to happen was:
You have to click away the 'Twitch Broadcasting Unavailable' message once after hitting the F6 key several times.

What happened was:
You have to click away the message according to the number of times you hit the F6 key, they sum up.

Additionally, even if you only hit F6 once, you still have to click on 'Cancel' twice.

Steps to reproduce:

• Make sure you do not have a Twitch account linked to your mojang account
• Hit F6 ingame several times
• Cancel each error message
