Auto merge of #13703 - Rafagd:my_changes, r=Ms2ger

Replacing Node.rootNode for Node.getRootNode.

- Changed the specification for the Node element to reflect the new standard.
- Changed the implementation of the NodeMethod.

I'm still waiting for some answers for the questions I've posted on #13699, but I'm already doing the pull request so I can get some feedback as well.
