Angular CLI + Angular 4 = IE10 doesn't work

I can't get IE10 to load a brand new Angular CLI project. There is no other code other than what comes with default Angular CLI package when you run 'ng new'.

I'm using Angular 4.2.4, @angular/cli 1.3.1 and IE 10.0.9200.16519

I have tried 'ng build' and 'ng build --prod' and both return the same error messages. The project runs on every other browser.

I have uncommented all polyfill lines (and installed everything as per instructions in the file) that are needed to run IE9, IE10, IE11 in the polyfills.ts of the project.

The 4 errors are:

Expected identifier polyfills.bundle.js, line 6127 character 67

var REACT_ELEMENT_TYPE = typeof Symbol === "function" && Symbol.for && Symbol.for("react.element") || 0xeac7;

Object doesn't support property or method 'bind' styles.bundle.js, line 279 character 3

update = applyToSingletonTag.bind(null, styleElement, styleIndex, false);

Expected identifier vendor.bundle.js, line 2056 character 71

exports.rxSubscriber = (typeof Symbol === 'function' && typeof Symbol.for === 'function') ?
Symbol.for('rxSubscriber') : '@@rxSubscriber';

Object doesn't support property or method 'defineProperty' main.bundle.js, line 132 character 1

Object.defineProperty(__webpack_exports__, "__esModule", { value: true });

Seems like 'Symbol', 'bind', and 'defineProperty' are the culprits.

I do see Symbol and Object es6 polyfills being included in the pollyfills.ts project file though:

****************************************
* BROWSER POLYFILLS
*/
/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
...
(+ all the other polyfills that are in the polyfills.ts file)

How do I get this going on IE10?
