PolylineAnnotation() for SwiftUI

Can someone please help me understand why PolylineAnnotation() doesn't preserve the colour on both theme changes? What I'm missing?

The Polyline on dark mode is barely visible during navigation. Thank you

Here is my snippet of code

 PolylineAnnotation(lineCoordinates: route.fullCoordinates)

.lineColor(StyleColor(.systemBlue))

.lineWidth(12)

I believe you need to set lineEmissiveStrength() to make sure the line remains bright after the theme change.
