Public summary
Desktop dialogs opened with MessageBox() or MessageDialog.Show() display the hard-coded English title "Message" when their title is empty. Empty titles should stay empty, while explicitly supplied titles should continue to appear unchanged.
This affects both MessageBox overloads and the desktop MessageDialog. No additional MessageBox title parameter is needed; developers can already use MessageDialog.Title for a custom title.
