markup partially decomposed, CSS decomposed
Test passes if you see a green block.
This should have a green background
Assertion: A partially decomposed class name will NOT match a fully decomposed CSS selector name.
The assertion will hold true only if the user agent does no normalization between class name and selector. Note that the current CSS specification does NOT require this normalization to take place.
This test replicates a scenario where the CSS was created by someone using NFD, and the page where the CSS is used is authored using, say, a Microsoft keyboard, which outputs only partially composed text (tone marks are not composed).
