Formatting bug in Component diagram

Question

When doing horizontal arrows to an interface with annotations, the arrowhead is missplaced.

For Example:

@startuml
[Object1] - Interface1
Interface1 <- [Object2] : Test Text
@enduml

With vertical conections it's working fine:

@startuml
[Object1] - Interface1
Interface1 <-- [Object2] : Test Text
@enduml

Thanks for the report.

Unfortunately, this is really a GraphViz/Dot issue : it's going to be difficult to turn around.

We have opened an issue on GraphViz side : https://gitlab.com/graphviz/graphviz/issues/1357

I hope that this will be taken into account!
