How do I cleanly delete elements from a Sidebar List in SwiftUI on macOS

I would like to give users the option to delete List elements from a SwiftUI app's sidebar in macOS.

Here's what I currently have:

import Foundation
import SwiftUI

@main
struct FoobarApp: App {

    @StateObject private var modelData = ModelData()

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(modelData)
        }
        .commands {

        }
    }
}

class ModelData: ObservableObject {
    @Published var myLinks = [URL(string: "https://google.com")!, URL(string: "https://apple.com")!, URL(string: "https://amazon.com")!]
}


struct ContentView: View {

    @EnvironmentObject var modelData: ModelData

    @State private var selected: URL?

    var body: some View {
        NavigationView {

            List(selection: $selected) {
                Section(header: Text("Bookmarks")) {

                    ForEach(modelData.myLinks, id: \.self) { url in
                        NavigationLink(destination: Text("Viewing detailed data for: \(url)") ) {
                            Text(url.absoluteString)
                        }
                        .tag(url)
                    }

                }
            }
            .onDeleteCommand {
                if let selection = selected {
                    modelData.myLinks.remove(at: modelData.myLinks.firstIndex(of: selection)!)
                }
            }
            .toolbar {
                Button("Selected") {
                    print(selected ?? "Nothing selected")
                }
            }

            Text("Choose a link")

        }
        .frame(minWidth: 200, minHeight: 500)
    }
}

When I select one of the sidebar links and press the delete button on my keyboard, the link does get deleted, but the detail view doesn't always get cleared.

Here's a gif of what I'm referring to:

I'd like for the detail view to revert back to the default text, Choose a link, after the user deletes a link. Is there a way to fix this?

Also, I noticed that ContentView.selected doesn't get cleared after a link gets deleted. Is this expected? (I included a Selected button which prints the contents of this variable)

I'm using macOS 12.2.1 & Xcode 13.2.1.

Thanks in advance.
