brief blank white screen while closing Minecraft on chromebook

Steps

1. launch Minecraft

1. Press esc

2. press ok

What I observed

I saw a white screen after I took those steps. The white screen lasts for maybe a second or 2.

Note: This glitch doesn't work when you close Minecraft in other ways. Like exiting out of the program with exit button at the top.

Whats suppose to happen

Nothing is suppose to show and it just closes. Like when you close Minecraft using the x button at the top.
