Аннотации KDoc не отображаются в Dokka, сгенерированном HTML

Question

В настоящее время я тестирую документацию Dokka, и некоторые сделанные мной аннотации не отображаются. Вот мои выводы:

1. Классы не показывают @sampleи HTML-теги <p></p>, <h1></h1>: Увидеть SimpleCalculator документация по классу
2. Если описание было под тегом html, оно не будет отображаться: см. enum class OPERATOR документация по коду
3. Методы не показывают @sample а также @property вообще: см. всю документацию по коду метода
4. Смешанное определение между @property а также @param, В объявлениях классов @param это один внутри <> (например Group<T>). Но в методах это один из параметров.

Пожалуйста, смотрите мой код:

package example
