Comment 1 for bug 1267118

This is an outstanding error in libcroco which is still there in upstream 0.6.8, I've patched our version of the code in revision 12887 to do a case-insensitive match on the lang pseudo-class.

I'm attaching my test file which contains three text elements. The first 'Lower case' is green, the second is 'Jap' is a false-positive indicator while the bottom 'Upper case' is the false-negative reported here and is red before the patch and green after it.
