Yeah this is a normal condition for non-machine piece which has been allowed to do that because it's just a type of non-powered barrier, so according to the prefabs technically each piece is still operating individually (like a wall) in that case. There are a number of other cases of this, because I'd have to go in manually and set each one to an alternate state, which is likely not even possible without new features in the scripting system.
I'll have to investigate whether it's feasible or not, but it might not be worth the time, we'll see.
