(Only tested on realms for bedrock, survival, in the end dimension) When hit by a shulker projectile and thus inflicted with levitation, the player will rise; often times, though, the player does not stop floating until their head is stuck in a solid block. With one block ceilings, the player can move to phase through the block entirely, still suffocating on the way. With ceilings more than one block thick, the player will get stuck, suffocating until they either mine out or the levitation effect ends.

Steps to replicate.

1. Get hit by a shulker projectile.
2. Stand still and wait for head to enter a block.

Observed Results:
The player will either phase through a one block ceiling or get stuck in a 2+ block ceiling; both causing suffocation.

Expected Results:
The player should stop levitating upon reaching a solid object.
