polyfilling promise using core-js-pure fails after zone.js is loaded, but works with core-js.

[JayaKrishnaNamburu]

I have a use-case, where an app is loading [email protected] which patches Promise in the browser. So, even if the browser natively supports Promise.allSettled. zone.js patches it by removing the support. So, the embed app tries to load it's own polyfill using core-js. I see, recently there is an issue reported that loading core.js along side with zone.js is breaking #953. And it's been fixed 9125de6 and released in 3.15 https://github.com/zloirock/core-js/releases/tag/v3.15.2.

Well, the fix seems to work only when the package is imported via core-js and not using core-js-pure. Here is an example reproduction. I am using a older version of zone.js in the example so it patches Promise and makes allSettled undefined.

import "zone.js";
import "core-js/modules/es.promise.all-settled";

console.log(Promise.toString());
console.log(Promise.allSettled);
console.log(window["__core-js_shared__"].versions);

import "zone.js";
import "core-js-pure/stable/promise/all-settled";

console.log(Promise.toString());
console.log(Promise.allSettled);
console.log(window["__core-js_shared__"].versions);

I looked into fixing the same, but seems the project structure changed quite a bit under core-js-pure and the plans for next. let me know how can i help.
