I just spent so long making an entirely white map and spent so much paper on duplicating it, just to find out that I couldn't place the item frames entirely around the room, ruining the entire point of the build. Literally took me like 15 hours just to get all of the snow and place it just to find out that I couldn't actually make the build I wanted to because item frames are considered blocks instead of entities in bedrock. The only reason I can think of that it would be that way is because of lag, but that shouldn't mean that an entire feature gets essentially removed from the game.
