This test failed because it relies on :lang for results, but :lang is not supported by this browser.

A :lang value will match a lang attribute value regardless of case differences in the script tag.

This tests a detail related to :lang support. If :lang is not supported, a message will appear and the test will fail.

Spec text: «The matching of C against the element's language value is performed case-insensitively.»
