Hello,
There is some drawing issue when teoz is enabled.
@startuml
!pragma teoz true
box "QuiteLongNameforBox"
participant abc123
participant bcd123
participant cde123
end box
box "Short"
participant abc124
participant bcd124
participant cde124
end box
@enduml
There is extra space on left in first box. Without teoz it is drawn correctly. Like on right with short name for box.
