LGTM! Could we add a test case about Response in https://github.com/angular/angular/blob/main/packages/zone.js/test/common/fetch.spec.ts
This commit updates the implementation of the `fetch` patch and additionally patches `Response` methods which return promises. These are `arrayBuffer`, `blob`, `formData`, `json` and `text`. This fixes the issue when zone becomes stable too early before all of the `fetch` tasks complete. Given the following code: ```ts appRef.isStable.subscribe(console.log); fetch(...).then(response => response.json()).then(console.log); ``` The `isStable` observer would log `false, true, false, true`. This was happening because `json()` was returning a native promise (and not a `ZoneAwarePromise`). But calling `then` on the native promise returns a `ZoneAwarePromise` which notifies Angular about the task being scheduled and forces to re-calculate the `isStable` state. Issue: angular#50327
