Spectator Chat Bug

When trying to spectate a friend's game the chat box will not be there. So I'm unable to see what is happening in all chat, nor am I able to just chat with friends while watching. The only way I have found to fix this is to quit spectating, and reconnect.. somethings this will take 3 or 4 maybe 5 times before it works.

I know this isn't a major bug, but it can be pretty frustrating :C

---- Also, is there any way to change the filter options while spectating? I have mine turned off but when I spectate the chat filter is always on.
