InspectorStyleSheet currently uses CSSRuleList::create(styleSheet, omitCharsetRules = true), and the omitCharsetRules forces the CSSRuleList constructor to clone the stylesheet's rule list. All rules other than style-rules and rules with internal rule lists are discarded by InspectorStyleSheet anyway, so we don't need to filter out charset rules beforehand.
