lang=, Inheritance from an ancestor, block elements
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 styling is defined for a block element using lang= but the language is only declared using a lang attribute on an ancestor element, the styling should NOT be picked up.
