auditTime(0, animationFrameScheduler) stops emiting unexpectedly.

Describe the bug

Since version 7.5.0, there is a weird interaction between different observables using animationFrameScheduler, especially auditTime(0, animationFrameScheduler), which stops emitting when other observables using the animationFrameScheduler started concludes after the first event is sent to the audit.

This causes problems with Angular CDK virtual scroll viewport which stops working when other things in the application use the animationFrameScheduler on observables which concludes.

It seems related to the same changes which caused https://github.com/ReactiveX/rxjs/issues/7017.

Expected behavior

Other observables should not have side effects on the animationFrameScheduler Action from auditTime(0, animationFrameScheduler) and auditTime should keep emitting regardless of the recycling of animationFrameScheduler actions.
