I was testing a TNT launcher when I accidentally hit the emote button then I realized after you do a emote your inventory will disappear then I hit it a second time and it turned my screen into a blue void. The only way to fix it is to log out then log in again. I think it only affects MCPE

How To Reproduce:

1. Do an emote
2. Do a second emote 

Observed Result:

Inventory disappears and screen turns into a blue void

Expected Result:

Inventory will not disappear and screen will not turn blue
