Focused Views Get Clipped When Using NavigationStack or Form in Split-Screen Layout on tvOS

When attempting to replicate the tvOS Settings menu layout, where the screen is divided horizontally into two sections, placing a NavigationStack or a Form view on either side of the screen causes focusable views (such as Button, TextField, Toggle, etc.) to be visually clipped when they receive focus and apply the default scaling animation.

Specifically:

• If the Form or NavigationStack is placed on the right side, the left edge of the focused view gets clipped.
• If placed on the left side, the right edge of the focused view gets clipped.

This issue affects any focusable child view inside the Form or NavigationStack when focus scaling is triggered.

Example code:

struct TVAppMenuMainView: View {

    var body: some View {
        VStack {
            Text("Settings Menu")
                .font(.title)

            HStack  {
                
                VStack {
                    Text("Left Pane")
                }
                .frame(width: UIScreen.main.bounds.width * 0.4) // represents only 40% of the screen
                .frame(maxHeight: .infinity)
                .padding(.bottom)

                Divider()
                
                NavigationStack {
                    Form { // All the buttons will get cut on the left side when each button is focused
                        Button("First Button"){}
                        Button("Second Button"){}
                        Button("Third Button"){}
                        Button("Forth Button"){}
                    }
                }
            }

            .frame(maxHeight: .infinity)
            .frame(maxWidth: .infinity)
        }
        .background(.ultraThickMaterial)
    }
}

How it looks:

What I have tried:

1. .clipped modifiers
2. .ignoresSafeArea
3. Modifying the size manually

Using just a ScrollView with VStack works as intended, but as soon as NavigationStack or Form are added, the buttons get clipped.

This was tested on the latest 18.5 tvOS BETA
