ScrollView content alignment when set to both axis

I'm having trouble sorting this out: 

The ScrollView when set to use both axis always shows the content centered. 

This is independent from the size of the content, wheteher it exceeds or not the size of the ScrollView.

I'm looking for a way to have the ScrollVIew showing the top of the content on load, and not the center. Is there any way to set this behaviour in SwiftUI?

struct ContentView: View {

    var greenRectHeight = 1400.0
    var blueRectHeight = 100.0
    var redRectHeight = 20.0

    var innerRectWidth = 200.0
    var outerRectWidth = 300.0

    var body: some View {
        NavigationStack {
            ScrollView([.horizontal, .vertical]) {
                ZStack {
                    Rectangle()
                        .strokeBorder(lineWidth: 1)
                        .frame(width: outerRectWidth)
                        .frame(height: greenRectHeight)
                        .background(.green)

                    VStack(spacing: 0) {
                        Rectangle()
                            .strokeBorder(lineWidth: 1)
                            .frame(width: innerRectWidth)
                            .frame(height: blueRectHeight)
                            .background(.blue)

                        Rectangle()
                            .strokeBorder(lineWidth: 1)
                            .frame(width: innerRectWidth)
                            .frame(height: redRectHeight)
                            .background(.red)
                    }
                }

                .navigationTitle("ScrollView")
            }
            .background(.yellow)
        }
    }
}
