How to remove a second search text on tvOS18?

I have an issue on tvOS 18 beta from Aug 20, where the search text is displayed twice, as in the image below.

Code to reproduce the behavior is trivial:

struct ContentView: View {
    @State private var searchText = ""

    var body: some View {
        NavigationView {
            Text("Some content...")
        }
        .searchable(text: $searchText)
   }
}

I did not find anything new in the API or documentation to disable it. Also, online searches for this specific issue did not produce any results.

I would like to show the same behavior on tvOS18, as on tvOS17, without the second search text.

Any idea on how to hide that second search text?
