TabView on WatchOS (SwiftUI)

I'm having trouble implementing the TabView component on watchOS - wondering if anyone knows something I'm missing. It works fine on my iOS target, but on watchOS, a TabView with a List lets me tap one item, but returning to the main view and then tapping a second item won't result in the second view being loaded again. It works fine without the tabview of course.

class Item: ObservableObject, Identifiable {
    let name: String
    init(name: String) {
        self.name = name
    }
}

struct ContentView: View {

    @State var contents: [Item] = [Item(name: "Test"), Item(name: "Test 2")]

    var body: some View {
        TabView {
            List(contents) { (item: Item) in
                NavigationLink(item.name) {
                    ItemView(item: item)
                }
            }
        }
    }
}

struct ItemView: View {
    @State var item: Item
    var body: some View {
        VStack {
            Text(item.name)
        }
    }
}
