Documentation Update? Uncaught SecurityError: localStorage is not available for opaque origins

[honzie]

I'm attempting to use mocha-jsdom with the instructions per https://www.npmjs.com/package/mocha-jsdom. However, I'm receiving an error from JSDOM that appears similar to what was commented in at jsdom/jsdom#2304.

I see this in a fresh install, with the following test:

const jsdom = require('mocha-jsdom');

describe('mocha tests', function () {
  jsdom();
 
  it('works', function () {});

A test repo, with only mocha and mocha-jsdom and chai is available at https://github.com/honzie/jsdom-mocha-error/blob/master/test/test-test.js.

Updating the jsdom() invocation with a non-about:blank (JSDOM default) URL works. Example:

  jsdom({
    url: 'https://example.org/',
  });

I'm wondering if the documentation should be changed accordingly, or if a default URL should be used in the library. If you'd like either of these changes made in a fork and a PR opened, please let me know.
