Angular 2+: стиль Primeng не работает в созданном / развернутом приложении angular-cli

Я выполнил инструкции в ответах Angular 2 - стиль PrimeNg не работает и получил он работает в автономном приложении, обслуживаемом ng serve.

Но когда приложение создается и развертывается, стили и тема Primeng не объединяются. Элемент управления Primeng отображается без стилей и выглядит странно.

Сборка выполняется с помощью node --max-old-space-size=4096 "./node_modules/@angular/cli/bin/ng" "build" "--prod" "--aot" "--env=test" "--sourcemap"
