So far, we've been testing that jQuery element iteration works with polyfilled Symbol & transpiled for-of via a Node test with jsdom with the Symbol global removed. Unfortunately, jsdom now requires Symbol to be present for its internal functionality so such a test is no longer possible. Instead, it's been migrated to an iframe test with transpiled JavaScript. This PR also enables us to use ECMAScript 2017 or newer in Node.js code. Closes gh-4305
