angular - Las anotaciones de clase personalizadas no funcionan en la compilación de producción después de actualizar a NG9

Las anotaciones personalizadas no se llaman en absoluto en la compilación de producción después de actualizar a Angular 9.
Al probarlo con ng serve funciona como de costumbre.
No hay errores en la consola.

Mi anotación personalizada:

@CustomSmartForm('calculatorForm')
@Component({
selector: 'calculator-form',
...
})
export class CalculatorFormComponent implements OnInit {...}

La función que debe llamarse cada vez que se establece una anotación en un componente:

import * as _ from 'lodash';

export function CustomSmartForm(formId: string) {
    return (target: any) => {
        const glb: any = window;
        glb.__smart_form_definitions = glb.__smart_form_definitions || {};
        const scope = glb.__smart_form_definitions;
        _.set(scope, formId, target);
    };
}

Pero no se llama para todos los componentes y no sé por qué.
Esto solo ocurre en la compilación de producción.
Usando lodash, esta función establece la definición de clase en el objeto scope en la ruta formId.
A partir de este objeto intento recuperar las definiciones de clase por formId más adelante en la función a continuación:

function getCustomFormDefinition(formId: string): any {
    const scope = (<any> window).__smart_form_definitions;
    return scope && scope[formId];
}
