Current workaround :

interface HeaderRestitutionProps {
  className?: string;
  title: React.ReactNode;
  subtitle?: React.ReactNode;
  rightTitle?: React.ReactNode;
  classModifier?: string | null;
  defaultClassName?: string | null;
}
const HeaderRestitutionFixed: (props: HeaderRestitutionProps) => JSX.Element = HeaderRestitution as never;
        
const MyComponent = () => (
      <HeaderRestitutionFixed
          classModifier="stackedRight" // no error
      />
);
