Most decorations beyond 8,388,608 block have 2D Graphics or 2D sprites.

I keep looking at bushes and flowers on my multiplayer server on my FireOS and my Nintendo switch and there 2D but,with a 3D hit box which is NON–SOLID and at the corner like,X=8,388,608 Y= Z=8,388,608 Making them 1D beyond this point but still with a 3D NON–SOLID hitbox, JUST WHAT?????
