title: Ensure that there is a back button on a desktop (Windows 10) PWA
body: <p>Mobile devices have a hardware back button, so this isn't an issue.</p>
  
  <p>However, on desktop (mainly Windows 10) PWA apps appear to <em>sometimes</em> have a back button in the top left corner.</p>
  
  <p>I want to either:</p>
  
  <ul>
  <li>Ensure this is always visible, or...</li>
  <li>Know that it hasn't so that I can add it to the app itself.</li>
  </ul>
  
  <p>I don't want to do both - if the back button <em>is</em> visible I don't want a second one in my app. I never want to show it when visiting the app in the browser.</p>
  
  <p>It appears like the <code>manifest.json</code> should control this, but the <a href="https://developer.mozilla.org/en-US/docs/Web/Manifest#display" rel="noreferrer"><code>display</code></a> options don't help.</p>
  
  <p>On Windows 10 it appears to depend on how the PWA is installed.</p>
  
  <p>Is there a way to ensure that the back button always appears?</p>
