在rmarkdown中使用选项卡时，防止TOC崩溃返回顶部

如何解决在rmarkdown中使用选项卡时，防止TOC崩溃返回顶部

在rmarkdown中，当使用浮动TOC和嵌套选项卡时，我遇到了一个问题，其中TOC返回到“顶部”选项卡。例如，如果我正在查看Even more details about Bar here选项卡中的Bar子选项卡，然后单击该子选项卡中TOC中的内容，则它将继续折叠TOC并返回到“顶部”标签。另外，如果我单击目录中一个子选项卡的标题，一旦我开始滚动，目录就会折叠回到“顶部”选项卡。下面的示例代码。

是否可以防止TOC的“未请求”折叠/返回“顶部”选项卡，将TOC锚定到当前选项卡或子选项卡？或者，目录可能只显示当前选项卡或子选项卡的目录项以防止此问题？
