如何将 tcolorbox 置于 KOMA-script 文章的部分标题中央

我正在尝试将零件标题居中。
这是 MWE：

输出如下：

我尝试了许多命令（正如您在 MWE 上看到的那样）但是框仍然在正确位置。

您知道我怎样才能将它移至中心吗？

重要提示：当我删除 tcolorbox 时，它工作正常（标题移动到中心） - 问题是当我添加颜色框时。

把事情简单化：

\documentclass{scrartcl}
\usepackage{tcolorbox}
\renewcommand*{\raggedpart}{\centering}
\renewcommand*{\partformat}{\partname~\thepart\autodot\enskip}
\renewcommand\partlineswithprefixformat[3]{%
  \tcbox{\underline{#2#3}}%
}
%\usepackage{showframe}% to see the page areas
\begin{document}
\part{Testpart}
\end{document}

居中零件盒

或使用twocolumn文档类的选项：

\documentclass[twocolumn]{scrartcl}
\usepackage{tcolorbox}
\renewcommand*{\raggedpart}{\centering}
\renewcommand*{\partformat}{\partname~\thepart\autodot\enskip}
\renewcommand\partlineswithprefixformat[3]{%
  \tcbox{\underline{#2#3}}%
}
%\usepackage{showframe}% to see the page areas
\begin{document}
\twocolumn[\part{Testpart}]
\end{document}

但请注意：此建议仅在您不需要换行符时才有效。并且\twocolumn始终开始新的一页。
