The HTML API has been behaving as if CSS class name selectors matched class names in an ASCII case-insensitive manner. This is only true if the document in question is set to quirks mode. Unfortunately most documents processed will be set to no-quirks mode, meaning that some CSS behaviors have been matching incorrectly when provided with case variants of class names. In this patch, the CSS methods have been audited and updated to adhere to the rules governing ASCII case sensitivity when matching classes. This includes `add_class()`, `remove_class()`, `has_class()`, and `class_list()`. Now, it is assumed that a document is in no-quirks mode unless a full HTML parser infers quirks mode, and these methods will treat class names in a byte-for-byte manner. Otherwise, when a document is in quirks mode, the methods will compare the provided class names against existing class names for the tag in an ASCII case insensitive way, while `class_list()` will return a lower-cased version of the existing class names. The lower-casing in `class_list()` is performed for consistency, since it's possible that multiple case variants of the same comparable class name exists on a tag in the input HTML.
