 // There is one LanguageState instance per tab.
 // It is used to determine when navigating to a new page whether it should
 // automatically be translated.
 // This auto-translate behavior is the expected behavior when:
 // - user is on page in language A that they had translated to language B.
 // - user clicks a link in that page that takes them to a page also in language
 //   A.
