Title not updated after OnAppearing for TabbedPage in NavigationPage

[TWEESTY]

Description

The title of the navigation page is not updated if we set the title after the "OnAppearing" event. We only have the problem with the "TabbedPage", so we don't have it with a classic "ContentPage".
If we set the title inside the "OnAppearing" method, the title is well updated.

The problem exists at least with Android API 33 and 29.
Microsoft.Maui.Controls v8.0.40.

Steps to Reproduce

1. Create a tabbed page in a navigation page
2. For example, override the "OnAppearing" method inside the TabbedPage with

protected override void OnAppearing()
{
	base.OnAppearing();

    this.Title = "On Appearing Title";

    var timer = Dispatcher.CreateTimer();
    timer.Interval = TimeSpan.FromMilliseconds(2000);
    timer.Tick += (s, e) =>
    {
        MainThread.BeginInvokeOnMainThread(() =>
        {
            this.Title = DateTime.Now.ToString();
        });
    };
    timer.Start();
}

Expected : Firstly, the title is "On Appearing Title", then the title is updated every two seconds with the date
Actual : The title is "On Appearing Title", and it doesn't change
