      map http-equiv content-language to -webkit-locale. This particular test tests
      that a dynamically added content-language is processed. This expectation may
      change, see bug. The HTML 5 spec decrees that http-equiv content-language be
      processed when it is

      In Firefox and IE adding the meta element dynamically doesn't seem to affect
      the page, but in Firefox the meta content-language displayed in "Page
      Information" is affected.
