Summary Optimization in Node.replaceChild() is not spec-compliant

We have an optimization in Node.replaceChild() to avoid doing any work when the reference child and the new child are the same node. This optimization is not spec-compliant: - https://dom.spec.whatwg.org/#concept-node-replace This is an issue because it is observable via Mutation observers / listeners or DOM ranges.
