SwiftUI View Modifier .ignoresSafeArea(.keyboard) not working as expected

Question

My SwiftUI View is pushed up by the keyboard despite using the .ignoresSafeArea(.keyboard) modifier:

import SwiftUI

struct PushUpView: View {
    @State var random = ""
    
    var body: some View {
        ZStack(alignment: .top) {
            Color.clear
            VStack {
                ForEach(0..<25) { id in
                    Text("Text: \(id)")
                }
                TextField("Hello, World!", text: $random)
                Spacer()
            }
        }
        .ignoresSafeArea(.keyboard)
    }
}

Pursuant to the following threads:

• swiftui-in-ios14-keyboard-avoidance-issues
• how-to-prevent-keyboard-from-pushing-up-the-view-in-swiftui
• swiftui-ios14-disable-keyboard-avoidance

I thought that by using Spacer(), and by putting the keyboard avoid-er on a ZStack that has a Color.clear background that takes up all available space I'd be safe.

Alas, the problem persists. What am I doing wrong?
