core

Is this a regression?

Yes

Description

When make my Angular app zoneless, protractor integration tests are failing. It does not wait for routing, network requests or any async work to complete.

I traced it back to Testability always declaring the app as stable. This is due to only looking at the NoopNgZone for stability. Please also make Testability consider PendingTasks just like ApplicationRef.
