See https://developer.mozilla.org/en-US/docs/Web/API/Node/childNodes#simple_usage This is typed weirdly, because apparently you should check for existence here. Technically doing `node.hasChildNodes()` would be correct, but since we tend to serialize stuff here or there I feel this is safer (and we already do that in other places too).
