[lang="es"], lang="mx-es"

Ignore this test. (lang= with lang attribute is not supported)
You can only get meaningful results for this test if the lang= selector works with the lang attribute, since it checks a detail with regard to that support.

Test passes if you see green below.


Assertion: When the lang= value uses a single subtag, it will not match against an attribute value where it appears in a different position.
