The lid of a shulker box block is missing a hover animation when it is open. Instead of slowly bobbing up and down, the lid will stay completely still in the air.

Steps to Reproduce:

1. Summon a shulker entity
2. Wait for it to open
   → observe result
3. Place down a shulker box
4. Open it
   → observe result

Observed Behavior:

The lid of the shulker box block will be totally still.

Expected Result:

The lid would hover up and down similar to the entity.

Notes:

May be invalid due to the hovering animation possibly being a passive breathing animation, but was reported anyways to be sure.
