markup precomposed, CSS partially decomposed
Test passes if you see a green block.
This should have a green background
Assertion: A partially decomposed CSS selector name will NOT match a fully precomposed class 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 markup was created by someone using NFC, and the CSS is authored using, say, a Microsoft keyboard, which outputs only partially composed text (tone marks are not composed).
