title: MacOS Toolbar Space makes Items disappear despite sufficient space
body: <p>I created a macOS App with a NavigationView and a Toolbar.
  Somehow next to my toolbarItem there is a lot of space.. So whenever I change the size of my apps window the toolbarItem disappears. Despite there is still a lot of space for my item.
  I did not find out how to reduce that space..
  Can you help me?</p>
  <pre><code>var body: some View {
      NavigationView {
      }
         .toolbar(content: {
            ToolbarItem(placement: .navigation) {
               Image(systemName: &quot;gearshape&quot;)
                  .frame(height: 20)
            }
         })
  </code></pre>
