自定义 KOMA-Script 章节标题中的垂直小页面对齐

Question

我有一个自定义的 KOMA-Script 章节标题，类似于cleanthesis。章节标题和章节编号应在底部对齐。

当章节标题有两行时，就会出现问题。第二行位于章节号下方：

\section{Test section}

\chapter{Test chapter with very long title}
\section{Test section}
\Blindtext[2]

\end{document} 

minipages如果我将from的参数更改t为b，我会在底部获得所需的垂直对齐。不幸的是，章节号和规则也会向下移动：

我想固定章节编号和规则的位置，然后将章节标题中的线条堆叠在一起，并与章节编号在底部对齐。

PS：请忽略红线的水平跳跃。这可以通过表格图形修复。
