This has been fixed in version 12.2.16 and 13.2.1 of @angular/cli.

See https://github.com/angular/angular-cli/issues/22606

Temporary fix

This is not really the solution, but a temporary fix
I had to add the following into my .browserslistrc file.

not ios_saf 15.2-15.3
not safari 15.2-15.3

Doing so will fix the error.

Solution

As @HeroWanders mentioned in his answer, this did get fix in the v12.2.16 of the @angular/cli library

I had the same error, what worked for me was also updating ng-packagr to 12.2.7. As far as I know, that's the only way to fix this without updating to Angular 13 (which I can't, because of an unlucky dependency).

see this comment on github or my SO post about this error
