How to copy List items within Navigation

I am currently working on a SwiftUI project and encountering an issue with the .copyable(_:) modifier. I want to copy the currently selected items in a List, and while using .copyable(_:) works outside of navigation components, it doesn't seem to have any effect when used within NavigationSplitView or NavigationStack.

Has anyone successfully implemented copying functionality within a navigation structure using .copyable(_:)?

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationSplitView {
            List(0..<10) {
                Text("row \($0)")
            }
        } detail: {
            CopyableList()
        }
    }
}

struct CopyableList: View {
    let strings = ["Alpha", "Beta", "Gamma"]
    @State private var selection: Set<String> = []

    var body: some View {
        List(strings, id: \.self, selection: $selection) {
            Text($0)
        }
        .copyable(Array(selection))
    }
}
