OS: any

What steps will reproduce the problem?
(1) Make sure your UI language is EN-US or any other language with a locale attached to it.
(2) Change target language to one not in chrome://language-settings.
(3) Observe that the target language got correctly added to chrome://language-settings.
(4) Now remove the language that just got added from chrome://language-settings.
(5) Go back to the translated page and translate again. Observe that the target language correctly switches back to English
(6) Go back to chrome://language-settings. English has been added to the bottom of the list.

What is the expected result?
Since English is already in the list as EN-US, don't add EN.

What happens instead?
