[breaking changes of rxjs6](https://github.com/ReactiveX/rxjs/blob/master/CHANGELOG.md#breaking-changes-7)\r\n\r\nAngular depends on core-js polyfill. but core-js's `Object.setPrototypeOf` polyfill needs IE11+ [you can check here.](https://github.com/zloirock/core-js#ecmascript-object)\r\n\r\nSo if Angular want to support IE10. need other polyfill like [set-prototype-of](https://www.npmjs.com/package/setprototypeof) or else.\r\n\r\nOr just add commented module import syntax like `classlist.js`.\r\n\r\nOr don't support IE10... 😢 \r\n\r\n\r\n## Expected behavior\r\n<!-- Describe what the desired behavior would be. -->\r\n\r\n\r\n## Minimal reproduction of the problem with instructions\r\n<!--\r\nFor bug reports please provide the *STEPS TO REPRODUCE* and if possible a *MINIMAL DEMO* of the problem via\r\nhttps://stackblitz.com or similar (you can use this template as a starting point: https://stackblitz.com/fork/angular-gitter).\r\n-->\r\n\r\nAfter uncomment some lines in `polyfill.ts` for supporting IE10 but.
