:lang, Inheritance from an ancestor, inline elements
Ignore this test. (:lang with xml:lang is not supported)
You can only get meaningful results for this test if :lang works with xml:lang, since it checks a detail with regard to that support.
Test passes if the second word below has a green background.
Assertion: When styling is defined for an inline element using :lang but the language is only declared using an xml:lang attribute on an ancestor element, the styling should still be picked up.
