if I add a legend to a sequence diagram and use the teoz layout the legend is too wide and the text/background y-offset does not match

If I deactivate teoz, or draw another diagram type then everything looks ok.
It can be reproduced with following sample


!pragma teoz true
' if you remove the comment of following line it looks ok
' !pragma teoz false

c1 -> c2 : call5
' Or if a component diagram is drawn
' [A]->[N]

<#transparent,#transparent>|<color:#000000>**Legend**</color> |
|<#438DD5><color:#3C7FC0> <U+25AF></color> <color:#FFFFFF> container</color> |
|<#85BBF0><color:#78A8D8> <U+25AF></color> <color:#000000> component</color> |
|<#transparent><color:#444444> <U+25AF></color> <color:#444444> container boundary</color> |

I rendered it
a) locally on my Windows machine (I used plantuml-mit-1.2023.13.jar that I avoided GraphViz problems too).
b) or via docker image plantuml/plantuml-server:jetty.

Thank you and best regards

PS.: orig C4 issue

Hi Th.

in https://github.com/plantuml/plantuml/issues/1575 the error is "Creole" related
but it can be reproduced with normal text too (I reproduced it via the docker image).

!pragma teoz true

' Sequence has wrong layout
 c1 -> c2 : call5
' Component has correct layout



Could it be that the legend size is calculated based on a wrong font?
sequenz too wide but

Looks like the issue arised between versions 1.2023.5 (OK) and 1.2023.6 (too wide).

OS: Windows, graphviz v9.0.0

plantuml-1.2023.4.jar  ✅
plantuml-1.2023.5.jar  ✅
plantuml-1.2023.6.jar  ❌(too wide)
plantuml-1.2023.13.jar (too wide)
snapshot 1.2024.0beta1 (too wide)

Sample diagram:

participant A
participant B

note across
| Item1 | 1 | 3 |
| Item2 | 2 | 4 |
end note
