[WASM/Skia] NavigationBar doesn't render when used with C# Markup

[kazo0]

Using NavigationBar with C# Markup just displays the default ContentTemplate of the implicit TextBlock for the NavigationBar.

run dotnet new install Uno.Templates::5.0.13
 

Using markup

dotnet new unoapp -preset recommended -markup csharp -o NavBarMarkup

Using xaml

dotnet new unoapp -preset recommended -markup xaml -o NavBarMarkupXaml

This is not specific to C# Markup, a simple XAML page where we initialize a NavigationBar in the code-behind and add it to the Page Content will have the same result
