<p>Test for <a href="https://bugs.webkit.org/show_bug.cgi?id=76701">bug 76701</a>:
map http-equiv content-language to -webkit-locale. This particular test tests
that dynamic changes to the meta element have no effect. This expectation may
change, see bug. The HTML 5 spec decrees that the pragma-set default language
be set only when the meta element is 
<a href="http://dev.w3.org/html5/spec/Overview.html#insert-an-element-into-a-document">inserted into the document</a>.
In Firefox and IE changing the element dynamically doesn't seem to affect the
page, but in Firefox the meta content-language displayed in "Page Information"
is affected.
