From OTRS - https://ticket.wikimedia.org/otrs/index.pl?Action=AgentTicketZoom;TicketID=10683826
Note - I am translating using google for this one
This is a change request from OTRS. The user would like the help and feedback page to default to the device language. I mentioned in the ticket that there is a language list at top of the page, but I figured it is worth passing on.
Translated from Japanese using google:
"Also, although the display language of Help and Feedback is set to English by default, it is better to set the default language for the language you set."
