selectors with different normalization
Test passes if these two squares are different colors.
Assertion: Selectors that only differ due to normalization should be treated as different.
The assertion will hold true only if the user agent does some normalization between class name and selector. Note that the current CSS specification does NOT require this normalization to take place.
Two selector names use different normalized forms. If the application normalizes both names, the second declaration should override the first.
