When updating children of a node, first update it's cached attribute
values. This prevents a situation where
UpdateCachedAttributeValuesIfNeeded() would be called on the same
node and potentially mark try to this->SetNeedToUpdateChildren() while
|this| is already in the middle of updating children.
