If you use "Broadcast" button on Minecraft PE (Bedrock), keyboard will not work at all within the game, it only works when in the stream chat. Please fix this issue as I am trying to stream myself building stuff (with command blocks) and typing is essential. (also it would be great if it works with YouTube) 

MOV_0431.mp4 shows the keyboard not working in chat when broadcasting.

MOV_0430.mp4 shows keyboard not working when a sign is placed when broadcasting.

(same thing happens with command blocks)
