<<Bug>>

What I expected to happen was the fence would ignore the invisible block

what happened was the fence was connection to the ghost block which is very distraction for some map maker buildings:

Steps to Reproduce:
1. place fence
2. put barrier block next to fence

*it does this in survival, creative and spectator and even adventure mode

don't get me wrong it looks kinda cool but its very annoying to see if your crossing a bridge and you see this
unless this is intentional its annoying or unless theres plans for a /give @p barrier slabs, then nevermind
