iOS 26 - ToolbarItem with .keyboard placement adds additional positive/negative top margin

Since iOS 26, when using toolbar items with .keyboard placement, the view inside the hierarchy which is pushed, does not directly stick to the toolbar anymore when a text field is focused, creating a gap, or moving the view below the toolbar. Focusing another field pushes the layout below the toolbar.

Minimal example to reproduce the issue.

import SwiftUI
import Foundation

@main
struct testfocusApp: App {
    @State var showSheet = false
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

struct ContentView: View {
    enum Field: Hashable {
        case body
        case title
    }

    @State var titleText = ""
    @State var bodyText = ""
    @FocusState private var focusedField: Field?

    var body: some View {
        NavigationView {
            VStack(spacing: 0) {
                ScrollView {
                    VStack(spacing: 16) {
                        TextField("", text: $titleText)
                            .onSubmit {
                                focusedField = .body
                            }
                            .background(Color.red)
                            .focused($focusedField, equals: .title)

                        VStack(spacing: 0) {
                            VStack {
                                Text(bodyText)
                                    .padding(.vertical, 9)
                                    .padding(.horizontal, 5)
                                    .hidden()

                                TextEditor(
                                    text: $bodyText
                                )
                                .focused($focusedField, equals: .body)
                            }
                        }
                    }
                    .padding(20)
                }

                Spacer()

                VStack(spacing: 16) {
                    Text("message")

                    Button {

                    } label: {
                        Text("Save")
                            .frame(maxWidth: .infinity)
                    }
                }
                .border(Color.red)
                .background(Color.green)
            }
            .background(Color.yellow)
            .border(Color.purple)
            .toolbar {
                ToolbarItem(placement: .keyboard) {
                    Button("Done") {

                    }
                    .border(Color.purple)
                }
            }
        }
    }
