      Item entities can glitch inside the piston's head (block 36) upon being moved, if they are inside cobweb/power snow, and under some special conditions.
      This issue is specially bad since powder snow being introduced (1.17) but it can be replicated in 1.14 with cobweb.

      How to Replicate:

      Open the world download attached in 1.14
      Power the command blocks, which will summon multiple item entities
      Power the piston

      Expected behavior:

      All entities move towards the next block, and exact same position for all

      Observed Behavior:

      Some entities glitch inside the piston head. This means they'll all randomly spread across the block.

      As mentioned earlier, this issue becomes specially problematic for powder snow (1.17+), since this can be moved by pistons. Powder snow is very commonly used for item aligners, to slow down entities, etc. It is crucial to fix this issue. A video showcasing the issue will be attached too (recorded in 1.21).
