title: swiftui - how to detect mouse hover over element in picker and present a popover
body: <p>I'd like to show a popover when the user hovers over an element in the picker.</p>
  <p>It doesn't work, it seems that the picker is grabbing the hover and not passing it through.</p>
  <p>I've also tried adding a button to the right side of the text and then when pressing it showing the popover, but the picker won't show the button when there is an <code>HStack</code> holding each row and each button</p>
  <p>Code is very standard:</p>
  <pre><code>struct MyView: View {
   @State var selected = .....
   @State var hovered = false // also tried setting this to true always for tests
   var body: some View {
    Picker(&quot;&quot;, selection: $selection) {
      ForEach(states) { s in
        Text(&quot;\(s.id)&quot;).popover(isPresented: $hovered) {
            Text(&quot;this is hovered&quot;)           
        }.onHover { (hover) in 
           hovered = hover
        }
      }
    }
   }
  }
  </code></pre>
