title: After upgrade to iOS 11.3 web app does not show full screen per apple-mobile-web-app-capable
body: <p>I have a web app that contains the meta</p>
  
  <pre><code>&lt;meta name="apple-mobile-web-app-capable" content="yes"&gt;
  </code></pre>
  
  <p>Before iOS 11.3, when "added to Home Screen" it would then open like a standalone app without the navigation bar. </p>
  
  <p>After 11.3 it now opens with the navigation bar in the browser.</p>
