            Bug ID: 163096
           Summary: window.navigator.language incorrectly returns all
                    lowercase string
    Classification: Unclassified
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Macintosh
                OS: OS X 10.11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Bindings
          Assignee: webkit-unassigned at lists.webkit.org

When calling window.navigator.language, Safari will return something like "en-us", whereas every other browser returns "en-US".

As per [MDN](https://developer.mozilla.org/en-US/docs/Web/API/NavigatorLanguage/language) and defined in [BCP47](http://www.ietf.org/rfc/bcp/bcp47.txt), valid Extended Language Subtags must be 2*3ALPHA (uppercase).

In the current web app I'm building, this caused havoc with our localization, as the "en-us" didn't match any languages we had localized strings for.
