title: SwiftUI NavigationLink issue with multi selections
body: <p>I have an issue with SwiftUI navigation. To show the issue I made a simple example of a list of cars and if the user clicks on it, it shows the car details:</p>
  <pre><code>struct ContentView: View {
      var cars = [Car(name: &quot;A&quot;), Car(name: &quot;B&quot;), Car(name: &quot;C&quot;), Car(name: &quot;D&quot;)]
      
      var body: some View {
          NavigationView {
              LazyVStack(spacing: 10) {
                 ForEach(cars, id: \.self) { car in
                     NavigationLink(destination: {
                         CarDetailsView(viewModel: CarDetailsViewModel(car: car))
                     },
                     label: {
                         CarRowView(car: car)
                     })
                 }
             }
          }
      }
  }
  
  struct CarDetailsView: View {
      @StateObject var viewModel: CarDetailsViewModel
      @Environment(\.presentationMode) private var presentationMode
      
      var body: some View {
          Button(&quot;Back&quot;) {
              presentationMode.wrappedValue.dismiss()
          }
      }
  }
  
  class CarDetailsViewModel: ObservableObject {
      @Published var car: Car
      
      init(car: Car) {
          self.car = car
      }
  }
  
  struct Car: Hashable {
      var name: String
  }
  
  struct CarRowView: View {
      var car: Car
      
      var body: some View {
          Text(car.name)
      }
  }
  </code></pre>
  <p>This works well when you select one car at the time. Unfortunatly with swiftUI I cannot disabled multi selection. If the user select multiple cars at the same time, and then go back to the car list sometime I get an error log:</p>
  <pre><code>SwiftUI encountered an issue when pushing aNavigationLink. Please file a bug.
  </code></pre>
  <p>At that moment, the car list is no longer responsive. It takes few attempt but it does eventually happen. I can only replicate this on iOS 15 so far. I also tried to do this without the viewModel and it still happen.
  Ideally I want to keep the NavigationLink inside the VStack because it makes the row dimming when the user selects it.</p>
