Use makeRefPtr?

I don't think this needs to be in the security component unless there is an actual security bug we're fixing.

This needs to be cast to RefPtr<ContainerNode>. Not sure how we do that in our code... or maybe you mean adding makeRefPtr in any case?

Yeah, reading the code, I don't think any of this use is "dangerous".

I'm confused. Given Node::parentNode() returns ContainerNode, calling makeRefPtr will surely make it RefPtr<ContainerNode>?

OK, I stand corrected. I had build errors when I tried yesterday, but probably that was something else. Will update the patch and land it.
