@broofa

Yeah. I reproduced the bug in Angular 8. I have updated Angular to v9 and the bug does not reproduce any more.

Thank you.

@anton-marchenko thank you for taking the time to pull together the reproduction.

I was able to reproduce the issue with Angular 8.

The key thing that fixed it for me was upgrading @angular-devkit/build-angular@0.801.3 to @angular-devkit/build-angular@0.901.12

@RezaRahmati can you give that a try?
