Shell.MenuItemTemplate Sometime Does Not Work

[david-maw]

Description

In a release buil a Shell.MenuItemTemplate which includes x:DataType="MenuItem" does not work correctly (the binding to the Text property does not seem to work).

For example:

    <Shell.MenuItemTemplate>
        <DataTemplate>
            <ContentView>
                <Label Text="{Binding Text}"
                       x:DataType="MenuItem"
                       />
            </ContentView>
        </DataTemplate>
    </Shell.MenuItemTemplate>

Will produce a blank line in a release build on Windows but correctly show the MenuItem Text property in a debug build.

Steps to Reproduce

1. Download the repository
2. Create and run a Debug build, you should see this:
3. Repeat with a Release Build and the MenuItem lines will be blank.

@XamlTest can you verify if this works in .NET7?

And based on that set if this is a regression or not?
