Swift ​Charts: ​Point​Mark annotation appears behind other ​Point​Marks

I’m using Swift Charts to show a scatter plot with multiple PointMarks. When the user selects a point, I attach an annotation to the selected PointMark to show a label like Strike 1.

I expected the annotation to render above all chart marks, but in practice nearby PointMarks can be drawn over the annotation text/background.

Simplified example:

Chart {
    ForEach(points.filter { !$0.isSelected }) { point in
        PointMark(
            x: .value("X", point.x),
            y: .value("Y", point.y)
        )
        .foregroundStyle(.black)
    }

    if let selectedPoint {
        PointMark(
            x: .value("X", selectedPoint.x),
            y: .value("Y", selectedPoint.y)
        )
        .foregroundStyle(.orange)
        .annotation(position: .top) {
            Text("Strike \(selectedPoint.number)")
                .padding(.horizontal, 8)
                .padding(.vertical, 4)
                .background(Capsule().fill(.orange.opacity(0.15)))
        }
    }
}
