Players can do x-ray if it is slightly stuck in the sand block

If the player is stuck in a block then slowly comes out, the player can see through the block. Players can see the closed room below. (This I use a lot, and I hope it becomes a feature, not a bug)

How to produce:

1. Put a solid bolock next to the player, 1X3
2. Squat beside that solid block
3. Place solid blocks that fall like sand on top of the player's head. 2 times
4. Let players get trapped inside that solid block (sand)
5. Slowly squat out of the sand block until it is no longer damaged but is still squeezed a little by the sand block.
6. X-ray will happen

you can see how to produce it here:
