SwiftUI: How to make 3 linked scrollviews (headers, columns, cells) scroll to topLeading in onAppear

Question

This answer shows how to link 3 ScrollViews (a horizontal ScrollView for column headers, a vertical ScrollView for row headers, and a horizontal/vertical ScrollView for cells) and how to scroll the cells ScrollView to topLeading in onAppear. However on ios 16.4 where when the screen first appears the rowsHeader scrollview is not scrolled to the top and the colsHeader scrollview is not scrolled to the left. When the table scrollview is first scrolled manually the rowsHeader and colsHeaders scrollviews jump to the correct offset. Does anyone know how to fix this? Thank you

struct ContentView: View {
    
    let columns = 20
    let rows = 30
    
    @State private var offset = CGPoint.zero

        HStack(alignment: .top, spacing: 0) {
            
            VStack(alignment: .leading, spacing: 0) {
                // empty corner
                Color.clear.frame(width: 70, height: 50)
                ScrollView([.vertical]) {
                    rowsHeader
                        .offset(y: offset.y)
                }
                .disabled(true)
            }
            VStack(alignment: .leading, spacing: 0) {
                ScrollView([.horizontal]) {
                    colsHeader
                        .offset(x: offset.x)
                }
                .disabled(true)

                                    .frame(width: 70, height: 50)

                .background( GeometryReader { geo in
