Reset to default system titlebar is broken

[HO-COOH]

Describe the bug

Simply set ExtendsContentIntoTitleBar=true then set it back to false, now you have a broken system titlebar. The inactive color is the same as active, and caption button foreground color is also bugged.
This issue only occurs on Windows 11.

Steps to reproduce the bug

1. Create a new WinUI3 packaged project C# project
2. Use this code

        public MainWindow()
        {
            InitializeComponent();
            ExtendsContentIntoTitleBar = true;
        }

        private void myButton_Click(object sender, RoutedEventArgs e)
        {
            ExtendsContentIntoTitleBar = false;
        }

3. Click the button

It makes quick scanning all the issues and finding out what's going on a really cumbersome process! Any reasonable developer contributing issues IMHO is basically able to use google and co. to get this information beforehand to contributing valuable time and effort. Just my 2ct., thx.
