Many elements have special parsing rules that end up limiting what kind of nodes can appear inside. For example, https://html.spec.whatwg.org/multipage/parsing.html#parsing-elements-that-contain-only-text is used for <xmp> and as a result there will be either no child node, or a single text node child.
Should <template patchfor> ensure that result will be the same as if it was parsed at the target location?
Test case:
<!DOCTYPE html>
<xmp id=target></xmp>
<template patchfor=target><span>hello</span></template>
Or should be behave exactly like setting innerHTML? https://software.hixie.ch/utilities/js/live-dom-viewer/?saved=13929 tests that and at least <xmp> behaves the same as the main parser. Spec is at https://html.spec.whatwg.org/multipage/parsing.html#html-fragment-serialisation-algorithm and I'm not very familiar with where it differs from the main parser.
