Calling it would indicate a bug, as it can only ever return false.

StyleRuleImport constructor always take a stylesheet as a parameter but clearParentStyleSheet is called in various places. Is there a scenario where the importRule will not have a parentStyleSheet? Good point. If you remove the @import rule from its containing style sheet before the call to CachedCSSStyleSheet::checkNotify() happens, you could possibly have an unparented @import rule. We should keep the null check that the old version of this code had.

(In reply to comment #23) > This would be more memory-efficient as OwnPtr<Vector<RefPtr<CSSRule>>> as CSSOM wrappers are rarely constructed. The are bunch of improvements like that that can be done but better leave those for future patches.

Cool then maybe the review tool was confused.
