When replacing form control which has async validator the status from statusChange stays PENDING #20424

[X] Bug reportCurrent behavior
When replacing form control with a new one which has asynchronous validator only PENDING status is broadcasted from statusChanges observable.
const myForm = new FormGroup({
myControl: new FormControl('simple input');
});
myForm.statusChanges
.subscribe(status => console.log(status));
myForm.setControl('myControl', new FormControl('another input', null, asyncValidator));Console will only print PENDING. Nothing more.
Expected behavior
Final VALID or INVALID status should be broadcasted after async validator finishes his job.

This issue still exists for me in ng v. 6.0.5. I registered myself to the statusChanges event and it is not fired for the result. I only get the notification for the transition to pending.
In essence this makes it currently quiet hard to use the async validator properly. Are there already some straight forward workarounds?

What about this issue? We still have trouble with this behavior. Is a fix anywhere near?

A fix is waiting to be reviewed/merged at #20806 for two years already.
Core team simply does not care about issues with forms.
Same goes with #18575
