ES6 Proxies in Angular Template

Question

I am using RxDB (essentially a wrapper for pouchdb using rxjs), in my Angular application. Each document in the database (called an RxDocument) is a ES6 Proxy. For instance, I could have and RxDocument like so:

 Object{
    arr : getter
    arr : setter
 }

However, when I try to reference this getter in an Angular template, it causes the browser tab to crash, as the NgZone freaks out. For instance:

<div *ngFor="let arr of this.document.arr"></div>

How can I reference the proxied value in a way that doesn't upset the functionality of Angular change detection?
