import { createRootFragment } from "https://deno.land/x/frugal@0.9.1/src/runtime/preact/hydrate/createRootFragment.ts";
A Preact 11+ implementation of the replaceNode parameter from Preact 10.
This creates a "Persistent Fragment" (a fake DOM element) containing one or more
DOM nodes, which can then be passed as the parent argument to Preact's render() method.
