* SUMMARY Web Inspector should better support for CSSOM StyleSheet mutations (insertRule/deleteRule). * NOTES Currently InspectorStyleSheet manages a ParsedStyleSheet, with extra "SourceData" parsed from the raw stylesheet text. The raw text however, will be missing rule mutations to the actual CSSStyleSheet, e.g. insertRule / deleteRule. Thus making an imbalance between the rule ordinals in the SourceData map and the actual CSSStyleSheet CSSRules.
