This was useful because nsRuleData in the old style system may not hold all the data, but the only subclass ServoSpecifiedValues is always able to hold any data, and thus passes NS_STYLE_INHERIT_MASK to mSIDS. Given this, this method and mSIDs seems to be useless and can be removed. MozReview-Commit-ID: 4vWcV4DRS2i
