title: How to force-navigate in UWP WebView to HTTPS web page with invalid/selfsigned certificate?
body: <p>Let's say I want to develop my own lightweight browser Store app for Windows 10 UWP. There will be TextBox for the Uri, Button for navigation and WebView for the rest of the page.
  When I navigate to HTTPS web page with valid certificate and valid TLS settings, it just works, but when I navigate to page with invalid/expired/selfsigned certificate like <a href="https://expired.badssl.com/" rel="nofollow">https://expired.badssl.com/</a>, I only got <strong>OnNavigationFailed</strong> event with <strong>WebErrorStatus.CertificateIsInvalid</strong>.<br>
  I found no mechanism for overriding this error and continue navigation, just like it's possible in standard browsers and even in Microsoft Edge, that should be built using the same UWP API.</p>
  
  <p>Is there a way, how to override the HTTPS error and navigate to the target page anyway? I know that there are security consideration, I just want to be able to do that.</p>
  
  <p>Thanks</p>
