Why is it that the .NET MAUI WebView is unable to open links to websites that are not its source?

Question

I am developing a NET MAUI mobile app that contains a WebView object.
The source website, mywebsite.com, is loaded correctly and all its internal links work. My aim is making sure that when a link to a different website, say, microsoft.com, is clicked, the website opens in the default browser of the user's mobile phone. Problem is, when I click on microsoft.com (or whatever other external link), nothing happens. Navigating event is not triggered with these external links whether the target in the HTML is set to _blank or not; the solutions provided here (https://stackoverflow.com/questions/74149533/maui-webview-target-blank-href-redirects-not-working-on-android/74150663#74150663) did not work for me. Navigating event is regularly triggered when clicking on links internal to mywebsite.com. Steps to Reproduce My MainPage.xaml.cs contains:

public MainPage()
    	{
            InitializeComponent();
            // Subscribe to the Navigating event
            proteoWebView.Navigating += OnNavigating;
            // Subscribe to the Navigated event
            proteoWebView.Navigated += OnNavigated;
        }
        private void OnNavigating(object sender, WebNavigatingEventArgs e)
        {
            // Check if the URL is external
            if (!e.Url.StartsWith("https://mywebsite.com"))
            {
                // Cancel the navigation in the WebView
                e.Cancel = true;
                // Open the URL in the default browser of the user's phone
                Launcher.TryOpenAsync(e.Url);
            }
        }

My MainPage.xaml contains:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="ProteoApp.MainPage"
             NavigationPage.HasNavigationBar="False"
             >
    <Grid>
        <WebView 
                 x:Name="proteoWebView"
                 Source="https://mywebsite.com"
                 Grid.Row="0"
                 Grid.Column="0"
                 VerticalOptions="FillAndExpand"
                 HorizontalOptions="FillAndExpand"  
            />
    </Grid>
</ContentPage>

Other informations: I am developing with Visual Studio 2022, .NET 7.0, and I have experienced the problem with the Pixel 5 - API 33 (13.0 Android) emulator.
