Shell.FlyoutContent does not update with hot reload (most likely an SDK issue)

[PureWeen]

Description

I tested this on WinUI and iOS

If you add Shell.FlyoutContent to replace the FlyoutItems the Flyout doesn't update.

REPRO:

1. In Visual Studio, create new MAUI app from blank template
2. Replace contents in AppShell.xaml with:

<?xml version="1.0" encoding="UTF-8" ?>
<Shell
    x:Name="shell"
    x:Class="MauiApp6.AppShell"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:local="clr-namespace:MauiApp6"
    Shell.FlyoutBehavior="Locked"
    Title="MauiApp6">

    <!--<Shell.FlyoutContent>
        <CollectionView BindingContext="{x:Reference shell}" IsGrouped="True" ItemsSource="{Binding FlyoutItems}">
            <CollectionView.ItemTemplate>
                <DataTemplate>
                    <Label Text="{Binding Title}" TextColor="Red" FontSize="18" />
                </DataTemplate>
            </CollectionView.ItemTemplate>
        </CollectionView>
    </Shell.FlyoutContent>-->

    <FlyoutItem Title='Home Flyout 1'>
        <ShellContent Title="Home 1" ContentTemplate="{DataTemplate local:MainPage}" Route="MainPage1" />
    </FlyoutItem>
    <FlyoutItem Title='Home Flyout 2'>
        <ShellContent Title="Home 2" ContentTemplate="{DataTemplate local:MainPage}" Route="MainPage2" />
    </FlyoutItem>
</Shell>

3. F5 to build and run on Windows (WinUI)
4. Ensure XAML hot reload is enabled
5. Open AppShell.xaml and uncomment the Shell.FlyoutContent

RESULT:
The look of the flyouts doesn't change:

EXPECT:
The flyouts should have a new look, like:

Verified this issue with Visual Studio Enterprise 17.8.0 Preview 1.0. Can repro on Windows platform.

Note to self: Remember to log a new bug that removing the initial value of Shell.FlyoutContent will not render the default flyout labels, only on Windows.
