Dynamic WebBrowser size
Add this JavaScript to the end of your HTML which should placed in the WebBrowser-Control:
function ResizeWebBrowser() {
    var _renderedHeight=document.body.firstChild.offsetHeight * 0.5; // because -ms-text-size-adjust: 150%;
    var _json = '{""rendered_height"" : '+_renderedHeight+'}';
On the Control, activate JavaScript and register a action for ScriptNotify:
<phone:WebBrowser Name="Browser" Height="100" IsScriptEnabled="True" ScriptNotify="WebBrowser_ScriptNotify" IsHitTestVisible="False" />
Now we can resize our WebBrowser-Control:
private void WebBrowser_ScriptNotify(object sender, NotifyEventArgs e)
    Dictionary<String, String> _json = (Dictionary<String, String>)JsonConvert.DeserializeObject(e.Value, typeof(Dictionary<String, String>));
    if (_json.ContainsKey("rendered_height"))
        this.Browser.Height = Int32.Parse(_json["rendered_height"]);
That's all and it works perfectly for me. With the Option IsHitTestVisible="False" the WebBrowser-Control can't zoom and scroll and it feels like a Formatted TextBlock.
