Title bar API causes apps to crash on Windows 10 (less often on Windows 11)

[wbokkers]

Describe the bug

On Windows App SDK 1.5.8 (and possibly on 1.6 as well) users experience crashes in (child) windows using title bar customization.

Steps to reproduce the bug

1. I have this code in the constructor of a Window:

     if (AppWindowTitleBar.IsCustomizationSupported())
     {
             _appWindow.TitleBar.ExtendsContentIntoTitleBar = true;
             _appWindow.TitleBar.IconShowOptions = IconShowOptions.HideIconAndSystemMenu;
     }

2. User opens (closes?) this Window
3. The app crashes on Windows 10.0.10945.5131 (But sometimes also on newer Windows 11 versions)

Expected behavior

No crash

NuGet package version

WinUI 3 - Windows App SDK 1.5.8

Windows version

Windows 10.0.19045.5131 (frequent). On Windows 11 less often.
