Bug: ng build cause warnings with pseudo-selectors in aws-amplify

[wasifnaeem]

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

Angular 16

Description

I had no issue with Angular 16. When I upgraded this to Angular 17, experience this issue with aws-amplify css selectors
