ToolbarItemGroup(placement: .topBarTrailing) draws differently since iPadOS 17.4

Consider the following sample code:

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationStack{ TabView{ }
                .navigationTitle("Titel")
                .navigationBarTitleDisplayMode(.inline)
                .toolbar{
                    ToolbarItemGroup(placement: .topBarTrailing){
                        TextField("Test2", text: .constant("Test2")).textFieldStyle(.roundedBorder)
                        Image(systemName: "1.circle")
                        Image(systemName: "2.circle")
                        Image(systemName: "3.circle")
                    }
                }
        }
    }
}

This yields a different (wrong) result since iPadOS 17.4. See attached Images. Even Apps compiled with Xcode 15.2 and run on a device using iPadOS 17.4 beta are suddenly affected! All my experiments to get the old behaviour back were unsuccessful. Does anyone know a way?
