Why can't partitions or rectangles have different BorderStyle in the same way they can have different BorderColor?

Question

skinparam partition {     

     BackgroundColor OldLace

     BackgroundColor<<Start>> PaleGoldenRod

     BackgroundColor<<FixedUpdate>> PaleGreen

     BorderColor BurlyWood

     BorderColor<<Start>> Black

     BorderColor<<FixedUpdate>> Black

     BorderStyle Dashed

     BorderStyle<<Start>> Solid  ' This is not applied to the partitions tagged with Start. Why?

     BorderStyle<<FixedUpdate>> Solid  ' This is not applied to the partitions tagged with FixedUpdate. Why?

}

Hello all,

1/ Here is an example with skinparam, where we observe the issue (on BorderStyle):

[Click to see on PlantUML online server]

2/ And an attempts with beta-style (where we observe a lot of issues):

<style>
activityDiagram {
  partition {
     BackgroundColor OldLace
     LineColor BurlyWood
     LineStyle 4 'This seems to be not applied
     LineThickness 1 'This seems to be not applied
  }
  .Start {
    BackgroundColor PaleGoldenRod 'This seems to be not applied
    LineColor Black 'This seems to be not applied
    LineStyle 0
  }
 .FixedUpdate {
    BackgroundColor PaleGreen 'This seems to be not applied
    LineColor Black 'This seems to be not applied
    LineStyle 0
 }
}
</style>
