title: SwiftUI can't tap in Spacer of HStack
body: <p>I've got a List view and each row of the list contains an HStack with some text view('s) and an image, like so:</p>
  
  <pre><code>HStack{
      Text(group.name)
      Spacer()
      if (groupModel.required) { Text("Required").color(Color.gray) }
      Image("ic_collapse").renderingMode(.template).rotationEffect(Angle(degrees: 90)).foregroundColor(Color.gray)
  }.tapAction { self.groupSelected(self.group) }
  </code></pre>
  
  <p>This seems to work great, except when I tap in the empty section between my text and the image (where the <code>Spacer()</code> is) the tap action is not registered. The tap action will only occur when I tap on the text or on the image.</p>
  
  <p>Has anyone else faced this issue / knows a workaround?</p>
