SwiftUI mode.wrapped.value() lifts scrollView

问题

As it's common practice to use, I have LazyVStack inside my scroll View.

I have 3 views.

1st view contains Header which can be shown or hidden, and all other content goes under the header

2nd view with button to present 3rd view (when 3rd view is presented I want header to disappear, it does, but there is blank space under, and when I come back to previous view with mode.wrappedValue.dismiss() it's lifted and I cannot access the last image from 2nd view.

import SwiftUI

struct MainView: View {
    var body: some View {
        TestView()
    }
}

struct TestView: View {

    let hideUserInfo = NotificationCenter.default
                .publisher(for: NSNotification.Name("HideUserInfo"))

    let showUserInfo = NotificationCenter.default
                .publisher(for: NSNotification.Name("ShowUserInfo"))

    @State
    var shouldShowHeader = true

    @State
    var selection: Int? = 0

    var body: some View {

        ZStack {
            VStack {
                if shouldShowHeader {
                    Text("Test")
                }
                NavigationView {
                    ZStack {
                        Color.green.ignoresSafeArea()
