Cushion Bug with Two Snow Layers

Cushion becomes unusable when quickly replaced with a stair or slab while placed over two snow layers.

Steps to reproduce the issue

1. Place two snow layers on the ground.
2. Place a cushion on top of them.
3. Quickly replace the cushion with any stair or slab.

Expected result
The cushion should remain functional, allowing players to sit on it even after replacing it with a stair or slab.

Actual result
The cushion remains inside after the replacement, but players can no longer sit on it. Tapping the cushion does nothing, and starts breaking the slab/stair instead (if used with Tap to Interact)

Please fix the cushion's interaction so it remains usable after this block replacement. Players should be able to sit on the cushion without accidentally breaking the stair or slab underneath it.
