/**
 * Create a querying function, bound to a document created from the provided
 * markup.
 *
 * Note that similar to web browser contexts, this operation may introduce
 * `<html>`, `<head>`, and `<body>` elements; set `isDocument` to `false` to
 * switch to fragment mode and disable this.
 *
 * @category Loading
 * @param content - Markup to be loaded.
 * @param options - Options for the created instance.
 * @param isDocument - Allows parser to be switched to fragment mode.
 * @returns The loaded document.
 * @see {@link https://cheerio.js.org/docs/basics/loading#load} for additional usage information.
