Entities on blocks pushed by pistons behave weirdly, especially on honey and soulsand

If a piston pushes a block with an entity on it (see video), the entity will move forward by more than 1 block (about 1.5 blocks). On retraction, the entity moves 1.5 blocks back to its initial position.

Honey is not sticky as it was when it was first introduced. If a piston pushes honey with an entity on top, the entity will move 0.5 blocks, and will not move back on retraction (I suspect it has to do with honey’s lower hitbox).

On soulsand, entities partially sink inside the block (armorstand base is not visible).
