ScrollViewProxy's scrollTo function fails to correctly scroll to the desired view when that view is embedded in a ForEach that is itself embedded in a ForEach.
ie. ScrollView - ForEach - ForEach - View.

example:

import SwiftUI
import PlaygroundSupport
let outerCount = 10
let innerCount = 2

struct MainView: View {
    var body: some View {
        ScrollViewReader { proxy in
            ScrollView {
                ForEach(0..<outerCount, id:\.self) { num in
                    VStack {
                        Text("\(num)").padding()
                        InnerView(start: num, proxy: proxy)
                    }
                    .frame(width:300)
                    .background(.red)
                    .onTapGesture {
                        print(num)
                        withAnimation {
                            proxy.scrollTo(num, anchor: .top)
                        }
                    }
                    .padding()
                }
            }.frame(height:800)
        }
    }
}

struct InnerView: View {
    var start: Int
    var proxy: ScrollViewProxy
    var body: some View {
        VStack {
            ForEach(start*outerCount+outerCount..<start*outerCount+innerCount+outerCount, id:\.self) { num in
                Text("\(num)")
                    .frame(maxWidth:.infinity)
                    .frame(height: 50)
                    .background(.blue)
                    .onTapGesture {
                        print(num)
                        withAnimation {
                            proxy.scrollTo(num, anchor: .top)
                        }
                    }
                    .padding(3)
            }
        }
    }
}

let view = MainView()
PlaygroundPage.current.setLiveView(view)
