IconShowOptions.HideIconAndSystemMenu doesn't take effect when AppTitleBar.ExtendsContentIntoTitleBar set to true

[Lightczx]

Describe the bug

As described as title,

AppWindowTitleBar appTitleBar = appWindow.TitleBar;
appTitleBar.IconShowOptions = IconShowOptions.HideIconAndSystemMenu;
appTitleBar.ExtendsContentIntoTitleBar = true;

After doing this, the system menu can still open by right click the drag rectangle. It seem like the drag area is handling message regardless of the setting.

Steps to reproduce the bug

Just add some code in a WinUI3 project

AppWindowTitleBar appTitleBar = appWindow.TitleBar;
appTitleBar.IconShowOptions = IconShowOptions.HideIconAndSystemMenu;
appTitleBar.ExtendsContentIntoTitleBar = true;

Expected behavior

The title bar area should not respond to the mouse right click.
