-!!! bug
-    I tried to put this into an collapsed example admonition,
-    but the PlantUML diagram get's always placed outside the admonition.
-    Same applies for a tabbed environment.
-
-Example:  
-__code:__  
-``````
-```plantuml
-queue "write\nmarkdown" as write
-queue "commit/push/\nmerge changes" as update
-queue "pipeline\ntriggered" as cicd
-queue "MkDocs\nMaterial" as MkDocsMat
-queue "transpiled HTML\nonline" as deployed
-
-write -right-> update
-update -right-> cicd
-cicd -right-> MkDocsMat
-MkDocsMat -right-> deployed
-```
-``````

-__result:__  
-```plantuml
-queue "write\nmarkdown" as write
-queue "commit/push/\nmerge changes" as update
-queue "pipeline\ntriggered" as cicd
-queue "MkDocs\nMaterial" as MkDocsMat
-queue "transpiled HTML\nonline" as deployed
-
-write -right-> update
-update -right-> cicd
-cicd -right-> MkDocsMat
-MkDocsMat -right-> deployed
