This allows posting a restyle that says that only the rule(s) from the SVGAttrAnimationSheet cascade level will be replaced, which avoids running selector matching. This is needed to land bug 977991 prior to landing bug 960465, since that requires replacing all levels that contain animations. (I'll rename this to match the name determined in bug 1057231.)
