CSS styling Beta - Sequence diagram - dots not colored with LineColor

Question

Hello,

When using Beta styling with CSS on a sequence diagram and changing the line color, it doesn't change the color of dots.

Example code:

@startuml

skinparam useBetaStyle true
<style>
sequenceDiagram {
    LineColor #000
}
</style>

participant X

...

@enduml

The line is black while the dots remain in the default red.

Hello A.,

With last version v1.2025.4, we can now have:

@startuml

<style>
sequenceDiagram {
    LineColor #0c0
    LineThickness 3
}
</style>
