SwiftUI: scrollEdgeEffectStyle(.hard, for: .all) bug with preferredColorScheme(.dark)

In the small example below, I have set .preferredColorScheme(.dark). I am pushing a view that has a List. I have a custom background color.

When .scrollEdgeEffectStyle(.hard, for: .all) is used, the pushed view top and bottom safe areas flash black before being replaced by the blue background color.

If I change this to .scrollEdgeEffectStyle(.soft, for: .all), the issue goes away.

If I do not set preferredColorScheme(.dark), the issue also goes away.

I filled FB18465023, but wonder if I am just doing something wrong? Video of sample running: https://www.youtube.com/shorts/87rWqHtdmKw.

    var body: some View {
        NavigationStack {
            VStack {
                Image(systemName: "globe")
                    .imageScale(.large)
                    .foregroundStyle(.tint)
                Text("Hello, world!")
                
                NavigationLink("Push New View") {
                    PushedView()
                }
                .buttonStyle(.glass)
                .padding()
            }
            .frame(maxWidth: .infinity, maxHeight: .infinity)
            .ignoresSafeArea(.all)
            .background(.blue)
        }
        .preferredColorScheme(.dark)
    }
}

struct PushedView: View {
    @State private var searchText = ""
    
    var body: some View {
        List {
            ForEach(1...30, id: \.self) { index in
                Label("Label \(index)", systemImage: "number.circle")
                    .listRowBackground(Color.blue)
            }
        }
        
        // This causes the top and bottom safe areas to start off black before
        // getting the blue background from below
        .scrollEdgeEffectStyle(.hard, for: .all)

        // This does not have the issue
        // .scrollEdgeEffectStyle(.hard, for: .all)

        .listStyle(.plain)
        .background(.blue)
        .searchable(text: $searchText, prompt: "Search labels...")
        .toolbar {
            ToolbarItem(placement: .topBarTrailing) {
                Button("Toolbar Button", systemImage: "questionmark") {
                    print("touched")
                }
            }
        }
    }
}
