Nested NavigationStack inside sheet doesn't work with presentation modifier

[PhilipDukhov]

When I push item into childNavigationPath, somehow it gets pushed to the root NavigationStack instead of the sheet one.

It's probably related to the fact that nested NavigationStacks doesn't work in general, but somehow system sheet modifier handles it.

Steps to reproduce:

1. Click Show sheet
2. Inside the sheet click Push Next

Expected behavior: new view pushed inside the sheet Actual behavior: looks like nothing happens, but when sheet is closed there's the pushed screen

struct ContentView: View {
    @State var childNavigationPath = NavigationPath()
    @State var isSheetShown = false

    var body: some View {
        NavigationStack {
            Button {
                withAnimation {
                    isSheetShown = true
                }
            } label: {
                Text("Show sheet")
            }
            .presentation(
                transition: .slide(
                    options: .init(
                        edge: .bottom,
                        prefersScaleEffect: true,
                        isInteractive: true,
                        options: .init(
                            shouldAutomaticallyDismissDestination: false,
                            modalPresentationCapturesStatusBarAppearance: true,
                            preferredPresentationBackgroundColor: .gray
                        )
                    )
                ),
                isPresented: $isSheetShown
            ) {
                NavigationStack(path: $childNavigationPath) {
                    Button {
                        childNavigationPath.append("Some")
                    } label: {
                        Text("Push Next")
                    }
                    .navigationDestination(for: String.self) { item in
                        Text(item)
                    }
                }
                .frame(maxHeight: .infinity, alignment: .top)
            }
        }
    }
}

Hmm, seems like a SwiftUI edge case that perhaps .sheet explicitly accounts for. I'll have to investigate if I can add similar edge case handling.

Ok I think I can provide a workaround! I have a prototype I just need to test more.
