将 tcolorbox 覆盖书签设置为位于其父级上方

我为我的添加了一个新环境康奈尔风格的笔记：titlednote

它允许为注释添加标题，注释还应在其下方生成书签term。但由于terms使用覆盖层实现，因此定义 的tcolorbox书签不在覆盖层下方。titlednoteterm

Date以下是书签应位于下方的示例Meeting Context 例子

本cornell.cls示例如下：

\ProvidesClass{cornell}

生成截图的样本如下：

\documentclass{cornell}

\title{Some meeting notes}

\begin{document}
\maketitle

\begin{titlednote}[Meeting Context]{Date}
    Wednesday
\end{titlednote}
\begin{titlednote}{Moderator}
    Max Mustermann
\end{titlednote}
\begin{titlednote}{Participants}
    \begin{itemize}
        \item A
        \item B
        \item C
        \item D
    \end{itemize}
\end{titlednote}

\end{document}

我尝试titlednode通过将 从一个覆盖更改term为一个单独的 来修改环境tcolorbox。这解决了书签的问题，但它引入了一个布局问题：

\NewDocumentEnvironment{titlednote}{ om }
{
    \IfNoValueF{#1}{
        \begin{term}{#1}
            #1
        \end{term}
    }
    \begin{tcolorbox}[
            enhanced,
            breakable,
            title=#2,
            bookmark*={level=2}{#2},
            enlarge left by=.34\textwidth,
            width=.66\textwidth,
            parbox=false,% restore main text formatting behavior
        ]
}
{
    \end{tcolorbox}
}

结果如下：

修改的解决方案

我没有找到一种方法来计算（动态）高度term tcolorbox以便使用负数vspace。这可以解决问题，但一定有办法解决这个问题。

@ThomasF.Sturm 在评论中提供了该问题的解决方案。为了完整起见，这里将其应用于我的问题。

不要在覆盖层中定义书签，而是在父级中定义书签tcolorbox。为了做到这一点，可以检查是否提供了术语的可选参数。

\NewTColorBox[]{term}{ m }
{
    width=.325\textwidth,
%    bookmark*={level=1}{#1}, %<< Redundant, now set by titlednote environment
}

\NewTColorBox[]{titlednote}{ om }
{
    enhanced,
    breakable,
    title=#2,
    IfValueT={#1}{bookmark*={level=1}{#1}}, %<< Set term bookmark only if it was provided
    bookmark*={level=2}{#2},
    enlarge left by=.34\textwidth,
    width=.66\textwidth,
    parbox=false,
    overlay unbroken={
        \IfNoValueF{#1} {%
            \node[anchor=north west, outer sep=0pt, inner sep=0pt] at ([xshift=-.34\textwidth]frame.north west) {
                \begin{term}{#1}
                    #1
                \end{term}
            };
        }{}
    },
    overlay first app={
        \IfNoValueF{#1} {%
            \node[anchor=north west, outer sep=0pt, inner sep=0pt] at ([xshift=-.34\textwidth]frame.north west) {
                \begin{term}{#1}
                    #1
                \end{term}
            };
        }{}
    }
}
