[lang|="cs-CZ"], lang="cs-Latn-CZ"


This test failed because it relies on [lang|=..] for results, but [lang|=..] is not supported by this browser.

A lang|= value with language and region subtags will NOT match a lang attribute value with language, script and region subtags.

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