      Marker-ArmorStands should not be able to be interacted with, but despite that, pistons can push them.
      Screenshots for visualization/proof attached.

      Steps to reproduce:

      • Place a piston, sticky or regular, pointing upwards
      • summon an ArmorStand on top of that piston, with:
      /summon ArmorStand ~ ~ ~ {Marker:1b,NoGravity:1}

      The piston can push the Marker-ArmorStand upwards.

      This affects all directions:

      • For horizontal directions make sure you summon it above the ground, standing on the ground and summoning it causes it to be underneath the piston head.
      • Pushing downwards only works if the hitbox of the ArmorStand (which is for Marker:1b ArmorStands about the height of the base plate) it at the position of the piston head.

      I can understand that it is "works as intended" that NoGravity:1-ArmorStands can be pushed by pistons, as they are entities, but it should not be the case for Marker:1-ArmorStands.

      From a mapmaker's perspective, it'd be a desirable outcome if Marker:1-ArmorStands could not be interacted with at all, aside from commands.
      So a pushing with pistons shouldn't be possible at all.
