Chrome exempts Google sites from user site data settings

In Google Chrome's "Cookies and site data" settings, accessible via the Preferences menu item or directly with chrome://settings/cookies in the address bar, you can enable the setting "Clear cookies and site data when you quit Chrome". However, I've discovered that Chrome exempts Google's own sites, such as Search and YouTube, from this setting.
