fromURL doesn't seem to automatically set the document's URL as expected

On this page it mentions that the document URL, for the purpose of resolving relative hrefs, should be set automatically when using fromURL, however this doesn't appear to be the case.

For instance, the following code outputs "/docs/intro" instead of "https://cheerio.js.org/docs/intro":

const cheerio = require("cheerio");

(async () => {
    const $ = await cheerio.fromURL("https://cheerio.js.org/");

    const href = $("a:contains(Learn)").prop("href");

    console.log(href);
})();
