UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36

Steps to reproduce the problem:
Here is my output:

> navigator.languages
["hu-HU", "hu", "en-US", "en"]

navigator.language
> "en-US"

(note that navigator.languages[0] seems the correct one for me because it's in the same order as I can see it's sent with Accept-Language HTTP headers)

What is the expected behavior?
navigator.language should be the same as navigator.languages[0]

https://developer.mozilla.org/en-US/docs/Web/API/NavigatorLanguage/languages

What went wrong?
The navigator.language is something else from the languages list (not the first element).

Did this work before? N/A
