WebView Renderer Migration does not load HTML or URL content on Maui compatibility renderer

[DanielCauser]

Hello!

I'm currently working on migrating our Xamarin Forms app into .net Maui. That said, I'm migrating the Xamarin Forms renderers and using the Compatibility path to simplify the migration process.

I created this discussion because I'm not sure if it is a bug or I'm missing something on my migration.

Here is the outcome of the migration of the Xamarin Forms into .Net MAUI. As you can see, the renderer in the XF platform loads the HTML content, whereas rendererer in the .NET MAUI compatibility mode does not.

I'm also attaching the zip of the projects I'm using to replicate the issue.
CustomRenderer.zip
The renderer looks like the one bellow. I pick the properties from the shared control and render them on the native webview.

namespace XamarinCustomRenderer.iOS.Renderers
{
    public class HybridWebViewRenderer : ViewRenderer<HybridWebView, WKWebView>
    {

        protected override void OnElementChanged(ElementChangedEventArgs<HybridWebView> e)
        {
            base.OnElementChanged(e);

            if (Control == null && e.NewElement != null)
            {
                _userController = new WKUserContentController();

                var config = new WKWebViewConfiguration
                {
                    UserContentController = _userController,
                    IgnoresViewportScaleLimits = true
                };

                var webView = new WKWebView(Frame, config)
                {
                    NavigationDelegate = new HybridWkWebViewDelegate(this),
                    UIDelegate = new WKWebViewUIDelegate()
                };

                webView.ScrollView.ShowsVerticalScrollIndicator = false;
                webView.ScrollView.ShowsHorizontalScrollIndicator = false;

                webView.LoadHtmlString(new NSString(e.NewElement.HtmlContent), null);
                //var link = new NSUrl(e.NewElement.URL);
                //var request = new NSUrlRequest(url: link);
                //webView.LoadRequest(request);

                SetNativeControl(webView);
            }
        }

Maybe the ViewRenderer fallls under this rule?

[DanielCauser]

Maybe not since ViewRenderer inherits directly from VisualElementRenderer

maui/src/Controls/src/Core/Compatibility/Handlers/iOS/ViewRenderer.cs

Line 14 in 573dfb9

public abstract partial class ViewRenderer<TElement, TPlatformView> : VisualElementRenderer<TElement>, IPlatformViewHandler
