[lang="en-GB"], lang="en-GB"

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: A lang= value with language and region subtags will match a lang attribute value with the same subtags.
