The best way to understand and demonstrate a problem is to write a minimal testcase.
Code:
<!DOCTYPE html>
<html>
<head>
<title>issue</title>
<style>
#issue {
color: green;
}
</style>
</head>
<body>
<p id="issue">This demonstrates the issue. It should be green but it's red!</p>
</body>
</html>
In lieu of that, refer to what I wrote previously.
