如何在页脚中用两行显示较长的章节名称？

Question

不久前我问过这个问题调整章节部分的宽度。

但是页脚还有一个问题。如果章节名称太长，页脚中的章节名称会在中间结束。有没有可能将高度优化为两行？

我尝试制作一个工作样本，但它不是最佳的......

\colorlet{ctcolorchapterline}{cyan}
\colorlet{ctcolorchapternum}{cyan}

\newcommand\mychapformat[1]{%
  \parbox[b]{\dimexpr\textwidth-3em\relax}{\raggedright#1}}
\titleformat{\chapter}[display]%
  {\usekomafont{chapter}}%
  {\vspace{-8em}\raggedleft{%
    {\color{ctcolorchapterline}%
        \rule[-5pt]{2pt}{5cm}}\quad%
