Let's say you were to place down an armor stand and name it TEST then use /setblock to place a chest on its location then place another chest somewhere nearby facing the same direction and put the same item in the same slot of both chests then run "/execute as @e[type=Minecraft:armor_stand,name="Crafting Table"] at @e[type=armor_stand,name="TEST"] if blocks ~~~ ~~~ (second chest location) all run say §aYes" you will get the error message shown in the picture and this glitch doesn't happen outside the beta/preview
