I will add also that if you change code in @hartez repro project in MainPage.xaml.cs to this:

    public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();

            var htmlSource = new HtmlWebViewSource();
            htmlSource.Html = @"<html><body><p>This is a WebView!</p>
            <div>
                <a href=""mailto:cfinley@fake.com"">Send an email</a>
                        </div>
                        <div>
                <a href=""tel:123456789"">Call me</a>
                        </div>
            </body></html>";
            TheWebView.Source = htmlSource;
        }
    }

you will see that tel: links on Android also do not work.

Is there any workarournd for this? the best I got so far is to reload the content of the WebView. In that way the error page will show and quickly be replaced by the original page

You can use the Navigating event. WebNavigatingEventArgs.Url will have the target, then you can do something like this:

            if (e.Url.StartsWith("http"))
            {
                Browser.OpenAsync(e.Url);
                e.Cancel = true;
            }
