Chrome browser language not necessarily first in languages list
It seems that in the latest version of Chrome (v. 59.0.3071.115), the display language is not necessarily the first one in the window.navigator.languages list (so taking languages[0] gets a wrong result).
See screenshots below:

Maybe it would be an idea to take into account the window.navigator.language value first and, if not found, use the first entry in the window.navigator.languages array.
P.S.: As far as I could see, now even the latest versions of IE and Edge set the window.navigator.language value.
Just tested with Chrome 62 and it seems quite the opposite: navigator.language apparently is the language of Chrome itself and navigator.languages[0] is the preferred language I set in the settings.
Perhaps you did not restart Chrome?
