Issue with ObjectPromiseProxy

controllers.application\.js

import Controller from '@ember/controller';
import { computed } from '@ember/object';
import { ObjectPromiseProxy, resolvingPromise, resultObject } from '../utils/object-proxy';

export default class ApplicationController extends Controller {
	regularObject = resultObject;

	//@computed() // uncomment this to get it to work 'somehow'
	get promiseObj() {
  	return ObjectPromiseProxy.create({
    	promise: resolvingPromise(resultObject)
    });
  }

	get promiseObjQuick() {
  	return ObjectPromiseProxy.create({
    	promise: resolvingPromise(resultObject, 0)
    });
  }

	// This is really to support something like this
  // Which cannot be in a route model hook
	// get myModel() {
  //	return this.store.findRecord('model', 1);
  //}

	// If i happened to be using an array ember-data has a solution that works   
	//  instances: computed('userIds.[]', function () {
  //      return DS.PromiseArray.create({
  //          promise: all(this.userIds.map(u => this.store.find('user', u)))
  //      });
  //  }),
}

<h1>ObjectPromiseProxy &amp; Octane Failure</h1>
<br>
<p>This twiddle will show that the classic controller will properly cause the UI to re-render when the promises resolve whereas the octane ones will not re-render at all.</p>
