title: Does TabView miss navigation clicks while redrawing?
body: <p>I have a vanilla TabView, an @ObservedObject, and a background task running which periodically updates the @Published field of the @ObservedObject.</p>
  <p>I've noticed that when the background task runs more frequently, and generates more changes to the @ObservedObject, the navigation tabs on the TabView become less responsive - they 'miss' taps. If I tap two or three times, I can normally change the view. The more frequent the background updates, the more often taps are 'missed'.</p>
  <p>So I'm wondering if the TabView somehow fails to notice taps while it is redrawing, or something like that?</p>
  <p>Any insights?</p>

  import Foundation
  import SwiftUI
  
  struct ContentView2: View {
      enum Tabs {
          case main
          case audio
          case preferences
      }
      
      @State var tab = Tabs.preferences 
      @ObservedObject var appState = Globals.appState
  
      var body: some View {
          TabView(selection: $tab) {
              MainView()
                  .tabItem {
                      Image(systemName: &quot;video.fill&quot;)
                      Text(&quot;Main&quot;)
                  }.tag(Tabs.main)
              AudioControlView()
                  .tabItem {
                      Image(systemName: &quot;speaker.fill&quot;)
                      Text(&quot;Audio&quot;)
                  }.tag(Tabs.audio)
              PreferenceView()
                  .tabItem {
                      Image(systemName: &quot;gear&quot;)
                      Text(&quot;Prefs&quot;)
                  }.tag(Tabs.preferences)
          }
      }
