This change aligns the stability of `ComponentFixture` with that of `ApplicationRef`, preventing confusing differences between the two as more APIs start using the `PendingTasks` that may not be tracked by `NgZone`. BREAKING CHANGE: `ComponentFixture.whenStable` now matches the `ApplicationRef.isStable` observable. Prior to this change, stability of the fixture did not include everything that was considered in `ApplicationRef`. `whenStable` of the fixture will now include unfinished router navigations and unfinished `HttpClient` requests. This will cause tests that `await` the `whenStable` promise to time out when there are incomplete requests. To fix this, remove the `whenStable`, instead wait for another condition, or ensure `HttpTestingController` mocks responses for all requests. Try adding `HttpTestingController.verify()` before your `await fixture.whenStable` to identify the open requests. Also, make sure your tests wait for the stability promise. We found many examples of tests that did not, meaning the expectations did not execute within the test body. In addition, `ComponentFixture.isStable` would synchronously switch to true in some scenarios but will now always be asynchronous. PR Close #54949
