[lang|="az-Arab-IR"], lang="az-arab-IR"


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 case-sensitivity of attribute names and values in selectors depends on the document language.»
