\n * \n * ```\n *\n * Elements by their ID are made available by browsers on the `window` object,\n * which is a security risk.\n * Using a prefix solves this problem.\n *\n * More information on how to handle clobbering and the prefix is explained in\n * Example: headings (DOM clobbering) in `rehype-sanitize`.\n *\n * ###### Unknown nodes\n *\n * Unknown nodes are nodes with a type that isn’t in `handlers` or `passThrough`.\n * The default behavior for unknown nodes is:\n *\n * * when the node has a `value` (and doesn’t have `data.hName`,\n * `data.hProperties`, or `data.hChildren`, see later), create a hast `text`\n * node\n * * otherwise, create a `
