What happened?

Since updating to the latest version of minecraft and itemsadder 4.0+. After updating the furnitures to item_display I've discovered lots of issues:

Furnitures requires multiple hits to be broken
You cannot one shot furnitures in gamemode creative and it's super hard to build with it
The barrier blocks hitboxes are wrong, if you have a 1x1x1 hitbox furniture, if you place the furniture on a wall and sometimes on ground you will have the barrier block be 1 block higher. A patch I found is add height_offset: -0.5 but the hitbox (the real one without the barrier block) is shifted randomly

Steps to reproduce the issue

create a furniture with a 1x1x1 hitbox
place it on a wall
See a barrier block being placed on the wrong position
change the hight_offset to -0.5
issue fixed but the break hitbox is shifted sometimes
to break a furniture it's often super hard to break it and even harder for builders when they are in gamemode creative
