Spectator mode is affected by pushed/pulled slime block

Slime blocks being pushed or pulled by a piston while the player is in spectator mode can push the player rather than just clip through the player

Steps on how to replicate:
1. Place a piston (any type) facing any direction with slime block on the front side
2. Go to spectator mode and position the player in the direction the piston is gonna push/pull the slime block
3. Activate the piston to push/pull the slime block
