SwiftUI List searchable animation issue

Question

I have just started learning SwiftUI and have created a basic View as follows:

import SwiftUI

struct ContentView: View {
    @State var searchText = ""
    @State var items = 0...5
    
    var body: some View {
        NavigationStack {
            List {
                ForEach(items, id: \.self) { item in
                    Text("Item \(item)")
                }
            }
            .searchable(text: $searchText)
            .navigationTitle("Test items")
        }
    }
}

When I tap the search field and the keyboard appears, the List jumps down the screen briefly, before animating. This can be seen in the following video:

I am using Xcode 14.2 and running the app on an iPhone 11 Pro (iOS 16.3).

I would be grateful if someone could let me know what I'm doing wrong here.

Thank you for your help in advance.

I have reduced the problem to its simplest form and the issue persists. I expect the animation to work smoothly without the content first jumping down the screen.
