Warning iconDescription in NumberInput component

[roberta-racco]

If I use the NumbeInput component written in this way:

      <NumberInput 
        className={`${className || ''} error-field`}
        id={`field-number`}
        labelText={""}
        hideLabel={true}
        onChange={onChange}
        value={3}
        max={maxValue}
        min={minValue}
        step={step || 1}
        iconDescription="actions"
        placeholder={placeholder}
        invalid={invalid || !!R.pathOr(false, ['error'], meta)}
        invalidText={invalidText || R.pathOr('', ['error'], meta)}
      />

I see in console the following warning regarding the iconDescription
