The court shall, in fixing the fees of any fiduciary, consider the compensation allowed to any person employed by the fiduciary under the provisions of section 633.84. If the court determines that the services rendered by such person were services that would normally have been performed by the fiduciary, the compensation of the fiduciary may, in the court's discretion, be reduced by all or any part of the compensation allowed to any such person.
