Description Matthieu Dubet 2023-03-22 16:48:28 PDT 
Currently, StyleRuleGroup is modeled exactly like CSSGroupingRule (being an intermediate class in the Rule <-> StyleRule hierarchy).

https://w3c.github.io/csswg-drafts/cssom/#the-cssgroupingrule-interface

We should favor composition instead of inheritance in general, and this is also a prerequisite of the CSS Nesting CSSOM implementation.
