Использование mdframed для форматирования записи индекса

Question

Я пытаюсь использовать mdframeдля форматирования записи индекса. Если я раскомментирую \def\UseMdframeForFormatting{}в MWE ниже (который пытается использовать mdframe), то я получаю ошибку:

Использование \@index не соответствует его определению

Код:

Не с , mdframedа с tcolorbox, это работает, если \begin{tcolorbox}ed \protect. Стиль tcolorboxдолжен быть адаптирован с \newtcolorboxна самом деле.
