      A ghost block will be created when an enderman puts down a moving piston head block.

      Steps to Reproduce:

      1. Summon an enderman in an enclosed space
      2. Modify what block it holds:
        execute as @e[type=minecraft:enderman] run data merge entity @s {carriedBlockState:{Name:"minecraft:moving_piston"}}
        
      3. Wait for it to place the block
        (If it's taking too long, tick sprint the game)
      4. Try and place a block where the enderman set down the moving piston head

      Expected & Observed Results:

      → A ghost block will be present where the enderman placed it. Despite the block appearing to be air, the player will not be able to interact with the block postion.
      → The moving piston head would either not be allowed as something an enderman can hold, something it can't put down, or it would just be destroyed when placed.

      Notes:

      1. In previous versions, the piston_extension block has been used in Enderman anti-griefing command block designs, because they could previously not place them and would also not have any visual appearance.
      2. Thee ghost block can be destroyed with TNT or /setblock
