Upon waking from a bed and a 2 block high pillar is touching the sides of it (right next to a wall), the player will be forcefully ejected inside the wall, even if there are air blocks around it.
I have attached a video showing how ridiculous this bug is.
From what I know, the bug didn't exist in the version prior. (19w12a)
