Change all the places that were including the deprecated parser, to include the new one instead, and then delete the old parser code. `ParentNode::query_selector[_all]()` now treat their input as a comma-separated list of selectors, instead of just one, and return elements that match any of the selectors in that list. This is according to these specs: - querySelector/querySelectorAll: https://dom.spec.whatwg.org/#ref-for-dom-parentnode-queryselector%E2%91%A0 - selector matching algorithm: https://www.w3.org/TR/selectors-4/#match-against-tree
