Shell.NavBarIsVisible="False" on page is ignored in 10.0.60 (regression from 10.0.51)

[SorenBech2]

Description

Setting Shell.NavBarIsVisible="False" directly on a page no longer hides the navigation bar in 10.0.60. This worked correctly in 10.0.51.

Steps to Reproduce

1. Create a .NET MAUI Shell app targeting net10.0-android
2. Set Shell.NavBarIsVisible="False" on a ContentPage (or derived page) in XAML:
   <ContentPage ...
   Shell.NavBarIsVisible="False">
3. Register the page as the root ShellContent in AppShell.xaml:

4. Run on Android (not tested on IOS)

The culprit is adding the following lines to Styles.xaml:
<Style TargetType="Shell" ApplyToDerivedTypes="True">

</Style>

If this line is added - to ensure default is visible - the value is not overwritten by a Shell.NavBarIsVisible="False" on the individual page - which I beleive it should. Works fine in 10.0.50,
