Upwards/downwards facing item frames require a block adjecent in order to be spawned.

      My goal has been to summon an item frame facing upwards, but it seems that you need a block to spawn the item frame, even if it wouldn't be needed to spawn it normally. See my shitty MsPaint diagram to see what I mean:

       

      Here is the code I've been using to summon the item frame:

       

      location.getBlock().setType(Material.IRON_BLOCK);
      		
      ItemFrame frame = (ItemFrame) gameBoard.getWorld()
          .spawn(gameBoard.getBlock().getLocation().clone().add(0, 1, 0),
              ItemFrame.class, 
              entity -> {
                  ItemFrame itemFrame = (ItemFrame) entity;
                  itemFrame.setFacingDirection(BlockFace.UP, true);
              });
      

      When run, it produces the following stacktrace:

      Caused by: java.lang.IllegalArgumentException: Cannot spawn hanging entity for org.bukkit.entity.ItemFrame at Location{world=CraftWorld{name=world},x=-111.0,y=116.0,z=-150.0,pitch=0.0,yaw=0.0} (no free face)

      This doesn't seem like logical behavior, leading me to believe this is not intentional.

      Attached is a reproduction plugin. Simply run /blackjack create to cause the behavior described.
