Problems with RxJS 7

[gonzalo-lorieto]

Is your feature request related to a problem? Please describe.
The whole angular universe didn't integrate the new version of rxjs (7.x) yet, even in version 14.

There are known issues with angular material that component events are being fired when they are not supposed to be fired with rxjs 7.x and not with 6.x.

ReactiveX/rxjs#6978

Describe the solution you'd like
Downgrade rxjs to 6.x until 7.x is fully supported

Describe alternatives you've considered
No other alternatives.

Additional context
None
