Game pause bug that wasnt Fixed from Version 1.11

Report : game dont pause if you exit or accedentaly Press the recent button that triggers the game loading screen that makes the game unpause, thats why i dont Make a elavator that made by magma Blocks Because i died on it before because of this, i have a Challenge that I only have 1 life ( because mcpe doent have Hardcore mode ) if i die and i will never play the world again, i was creating a Elevator for my mob farm then my mom Called so the game minimized and It happens when i get back to the game and its still loading And i Hear a Sound that damaged my character And when the loading was done Then my character died to, so its better to add a Gamepause. So i also want a button Where its easy to press to change view like back front and first person view i will add a Picture soon. Thats all plss i hope for accepting this suggestion because it will help players like me.
