Баг: при правке постов `& l t ; i >` превратилось в ` < i > `

0

3

Создал пост в Markdown, в нём несколько раз вставил

`&lt;i>`

Затем полез добавить предложение. Сохранил, не глядя. Обнаружил, что все они преобразовались в

`<i>`

Дополнение:
HTML entity name и entity number в обычном тексте сразу преобразуются в соответствующий символ. В блоках кода отображаются без изменений.
При правке стартового поста они также не меняются. Это — правильное поведение.
При открытии для правки постов-ответов пользователь получает преобразованные символы в блоках кода. Это — баг.
