DesktopWindowXamlSource window in taskbar in Windows10 while using WindowsXamlHostElement with CaptureElement

Describe the bug

I see DesktopWindowXamlSource window in taskbar in Windows10 after a dialog with WindowsXamlHostElement and CaptureElement as a WindowsXamlHostElement child is closed. There is a test WPF application. Main window contains only a buttton that opens another dialog. This dialog has olny WindowsXamlHostElement

  <Grid>
        <xamlhost:WindowsXamlHost x:Name="XamlHost1" />
</Grid>

or with InitialTypeName (it makes no difference)

  <Grid>
        <xamlhost:WindowsXamlHost x:Name="XamlHost1" InitialTypeName="Windows.UI.Xaml.Controls.CaptureElement"/>
</Grid>

In the dialog constructor: XamlHost1.Child = new CaptureElement();

Optionally it can be done (it makes no difference)

XamlHost1.ChildChanged += XamlHost_ChildChanged;
...
//closed event handler
 private void OnDialogClosed(object sender, EventArgs e)
        {
            XamlHost1.Child = null;
        }

       private void XamlHost_ChildChanged(object sender, EventArgs e)
        {
            var xh = sender as WindowsXamlHost;
            if(xh != null && !xh.IsDisposed)
            {
               xh.Dispose();
            }
        }

On button press the dialog appears, after dailog is closed one can see a DesktopWindowXamlSource window in taskbar. It is reproducible on Windows10 22H2, but not reproducible on Windows11.
