-  // in the message. Chrome UI strings are localized string and therefore they
-  // should have the same alignment and directionality as those of the Chrome
-  // UI. For example, in RTL locales, even though some strings might begin with
-  // an English character, they should still be right aligned and be displayed
-  // Right-To-Left.
