I once played some minecraft, and then had to go away. I put my switch to standby mode, because i dont wanted the game to keep running while i was gone. But when i got back and started the game again, i only saw a death screen. Something had killed me while i was not here, even though my Switch was in standby mode. I noticed this already very often. The game keeps running in the background, even if the console is on standby mode. Every other game I own stops. 
I recently created a Issue for this, but it was marked as "worked as intendet".
This just CANT be intended if EVERY other game pauses when I turn of my console. 

Steps to reproduce:
Just turn the console into standby mode. 
If you come back, you will see that the game was running.

You can stand somewhere in survival mode and maybe get killed,
you can look at the sky, if you come back, you will see that the sun has moved while you were gone.
