Navigation in IPad SplitView in iOS 14.5 beta is completely broken

• missing Back-button in navigationBar.

• the views change place. Views that originally located in the right column are now moved to sideBar. This looks really weird and really broken.

• also the navigationLinks remain highlighted when the app is used in the splitview mode.

• Create a new app and replace the ContentView with my code block.

• Open the sample app with any iPad simulator running iOS 14.5 beta 3 in Xcode 12.5 Beta 3

• Drag another app alongside the sample app and in split view so that the sample app becomes as narrow as possible.

• Navigate to last view in sample app.

• Exit the split view mode by making the sample app full window size again

• Now you see how broken the sample app is. If you use iOS 14.4 simulator, the app has no problems.

                    View1()

        .NavigationViewStyle(DoubleColumnNavigationViewStyle())
    }
}
struct View1: View {
    var body: some View {
        List {
            NavigationLink(
                destination: View2(),

                NavigationLink(
                    destination: View3(),
