[UWP] WebView height gets wrong height randomly

Question

Hi,

I have loaded html content on a web view and tried to set the webview height using "ScriptNotify" and "NavigationCompleted" events. I need to do some UI related stuff depending on webview height like showing a button, enabling/disabling button, etc.

But sometimes I notice, it gets more height than it requires when opening the webview and it shows cached UI explained above. Seems like it requires a considerable delay to open a webview one after another.

private async void NCWRWebView_NavigationCompleted(WebView sender, WebViewNavigationCompletedEventArgs args)
            {
                    int heightScroll = 0;
                    var heightScrollStr = await webView.InvokeScriptAsync("eval", new[] { "document.body.scrollHeight.toString()" });
                    if (int.TryParse(heightScrollStr, out heightScroll))
                    {
                        webView.Height = heightScroll;
                    }
                   if (webView.Height > scroll.ActualHeight)
                    {
                        addButton.Visibility = Visibility.Visible;
                        cancelButton.IsEnabled = false;
                    else
                    {
                        addButton.Visibility = Visibility.Collapsed;
                        cancelButton.IsEnabled = true;
                    }
    }

I found similar thread to this. https://social.msdn.microsoft.com/Forums/en-US/4b09e2e1-90bc-4135-82fc-10d9067f0c6b/cuwpwebviewhow-to-resize-webview-height-based-on-html-content-in-windows-10-uwp?forum=wpdevelop

Is this issue addressed recently or is there any way to fix this issue?

Thanks
