[Android] [Shell] Tabbar disappears before navigation

[kubaflo]

Description

When using Shell.Current.GoToAsync("//DetailsPage"), if DetailsPage has Shell.TabBarIsVisible="False" and takes some time to load (which is not that uncommon), the navigation experience on Android is poor because the tab bar disappears before the user is fully navigated to the page. On iOS, this works correctly.

This delay causes a visual inconsistency where the tab bar disappears too soon, making the transition feel unpolished.

iOS works fine	but Android...

Steps to Reproduce

The DetailPage

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
        xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
        x:Class="Maui.Controls.Sample.DetailPage"
        Shell.TabBarIsVisible="False"
        BackgroundColor="Green"
        xmlns:local="clr-namespace:Maui.Controls.Sample">
<ScrollView>
        <VerticalStackLayout
                x:Name="CV">
                <BindableLayout.ItemTemplate>
                        <DataTemplate>
                                <Image Source="dotnet_bot.png"/>
                        </DataTemplate>
                </BindableLayout.ItemTemplate>
        </VerticalStackLayout>
</ScrollView>
</ContentPage>

public DetailPage()
{
	InitializeComponent();
	BindableLayout.SetItemsSource(CV, Enumerable.Range(1, 4000).Select(i => $"Item {i}").ToList());
}
