title: Why are WebRTC methods missing when run within a Microsoft.Toolkit.Forms.UI.Controls.Webview?
body: <p>In a .NET Framework 4.6.2 Windows App, I am attempting to run some WebRTC capabilities, in JavaScript, within the WebView control.  The control is from Microsoft.Toolkit.Forms.UI.Controls.Webview (v6.1.1).</p>
  <p>When I try to use <code>RTCPeerConnection.AddTransceiver()</code>, or <code>RTCPeerConnection.GetTransceivers()</code>, I receive the error:
  <code>Object doesn't support property or method 'addTransceiver'</code></p>
  <p>When run directly within Edge, the code executes as expected.</p>
  <p>Why the difference, and how can I see the exact API that is used within the WebView control context?</p>
