FlyoutItem text disappears in Release mode, but not in Debug mode

[DM-98]

Description

The issue is when you apply x:DataType="local:AppShell" in AppShell.xaml, the text in LayoutItem completely disappears when running in Release mode. Everything works fine in Debug mode.

The issue is also described in #14865. After many hours of testing due to having to test only in Release mode, I found the bug.
It happens when you apply x:DataType="local:AppShell" on it.. Which is unfortunate since I'd like compiled bindings on it for improved data binding performance...

Steps to Reproduce

1. Create a new .NET MAUI App
2. Open AppShell.xaml
3. Make a wrap the ShellContent with a Flyoutitem
4. Write <Shell x:DataType="local:AppShell" ...>
5. Run in Debug to see that the text is visible, and then run in Release, and it's invisible.

Did you find any workaround?

To remove the x:DataType="local:AppShell" in <Shell...>, which is not a good workaround since we lose compiled databindings.

Looking at your code, I see the x:DataType="local:AppShell" in <Shell>, but there is no data binding on that object so the binding context will never be AppShell.

Doesn't matter, this is simply a reproduction repo. Either way, it will still bug out with the text disappearance in release (tested with our product at another private repo).
