I was messing around with bees and started spawning lots of them in a plains biome. I then saw a baby bee suffocate under a block inside a lake. I then started messing around with the bug to see if it would happen again.

I expected they wouldn't suffocate and would be fine.

What actually happened was they started to suffocate while trying to fly out.

Steps to create the bug:
1. spawn about 10 bees or more (adults and babies) in an underground hole with a width and length of 4 blocks and a height of 1 block.
2. break 1 block on the ceiling.
3. watch and listen for any form of suffocation as they try to fly out of it.
