The bug
If you try to build this piston elevator (or similar) in 1.11 versions, you will end up falling through the pistons for some reason. This elevator works perfectly in 1.10.2 and below, however.

I've attached one of the worlds this bug occurred in, however, it seems to appear consistently in all worlds.
When a player is sitting atop an upward facing piston with a block on top, it seems to redirect the player about a fourth of a block in a random direction. that seems to make the player clip into the wall which is causing the player to collide with a block above them. since the game prioritizes the block above the players head collision wise, the pistons move up into the player. i hope this gets fixed soon because virtually all piston elevators are broken, aside from using them in very specific positions which is a pain.
still an issue in 1.14.60
Related closely to MC-159503, only this setup does not have a block that is spit out, but intsead the player is clipped through the piston head.
Please attach the world here.
