This is mimics a keyboard toolbar, but uses safeAreaBar instead. This allows the bar to have custom layout properties (like bottom padding). iOS 26.0.1 has a bug where toolbar items with keyboard placement sit directly on the keyboard with no bottom padding whatsoever.

	import Combine
	import SwiftUI

	struct ContentView: View {
	@State var text = ""
	@State var keyboardObserver = KeyboardObserver()
	@Namespace var union

	var body: some View {
	VStack {
