NumberBoxCrashRepro

This repository shows a crash in WinUi, when a number box is opened in a new window where the opt SpinButtonPlacementMode is set to Compact.

Steps to reproduce

Clone the repository.
Open the solution in Visual Studio.
Build the solution.
Run the application.
Click the "Click Me" button on first window.
Click the number zone in the NumberBox in the new window (so that the flyout with the spin buttons is shown at least once)
Close the secondary window
Click the "Clicked" button on first window.

The application should not crash.

The application crashes with an UnhandledException.

Do not use SpinButtonPlacementMode.Compact but Inline or Hidden.
