Q/Report: Teoz not working?

[chipbite]

Hello!
Very interesting project!! So cool!

I immediately tried one of my recent diagrams and ran into some trouble, however.
First, it was veeerrry slooooowwww to render after a paste (say 90 loc). But after that, when done - it was like a skeleton, all the messages missing!
So, I started to see what could be wrong.... after a short while I found a:

Problem: teoz renderer is not working

So, this simple diagram will not render as intended:

@startuml
!pragma teoz true

a->b: foo
& b->c: bar
@enduml

Expected:

(from: https://www.plantuml.com/plantuml/uml/SyfFKj2rKt3CoKnELR1Io4ZDoSa70000)

Actual:

This may be a known issue - so I searched but could not find any mention of teoz.
So here is one reporting this!

Thanks again!
