title: Cordova app not displaying correctly on iPhone X (Simulator)
body: <p>I tested my Cordova-based app yesterday on the iPhone X Simulator in Xcode 9.0 (9A235) and it didn't look good. 
  Firstly, instead of filling the full screen area, there was a black area above and below the app content.
  And worse, between the app content and the black was two white bars.</p>
  
  <p>Adding <code>cordova-plugin-wkwebview-engine</code> so Cordova renders using WKWebView (not UIWebView) fixes the white bars.
  By my app is not migrated from UIWebView to WKWebView due to performance and memory leak issues when using <code>cordova-plugin-wkwebview-engine</code> which occur when loading images downloaded from Inapp Purchase hosted content into an HTML5 canvas (direct <code>file://</code> access by the Webview is not possible due to security restrictions in WKWebView so the image data must be loaded via <code>cordova-plugin-file</code>).</p>
  
  <p>These screenshots show a test app with a blue background set on the <code>&lt;body</code>>. 
  Above and below UIWebView, you can see the white bars, but not with WKWebView:</p>

  <p>Both Cordova Webviews exhibit the black areas when compared to a native app which fills the full screen area:</p>
