multicol环境下文本垂直对齐异常问题求解

我尝试让multicol环境中两栏文本实现垂直对齐，已消除已知的间距/跳格（如parskip、section前后间距）。但进入Results章节后，对齐出现偏移。我使用的figure环境、标题及subsection仅通过baselineskip的倍数设置间距，表现正常，但新章节前似乎被插入了额外间距。

最小工作示例（MWE） #

\documentclass[11pt, a4paper]{scrbook} 
\usepackage[top=2cm,bottom=2cm, includehead, headheight=0.5cm]{geometry}
\setkomafont{disposition}{\fontfamily{lmss}\normalfont}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[singlelinecheck=off, font={sf, bf}, labelfont=bf,    
    labelsep=period, margin=0cm,skip=0pt, belowskip=0pt]{caption} 
\usepackage{graphicx}
\usepackage{setspace}
\usepackage{lipsum}

\newenvironment{Figure2col}[1]
  {\par\noindent\minipage[][#1\baselineskip][t]{\linewidth}}
  {\endminipage\par}

\usepackage{multicol}
\setlength{\multicolsep}{0pt plus 0pt minus 0pt}

\RedeclareSectionCommand[
  runin=false,
  afterindent=false,
  beforeskip=0pt,
  afterskip=0pt]{section}
\RedeclareSectionCommand[
  runin=true,
  afterindent=false,
  beforeskip=\baselineskip,
  afterskip=30pt]{subsection}
\RedeclareSectionCommands[
  runin=true,
  beforeskip=0pt,
  afterskip=0pt]{paragraph,subparagraph}

\setkomafont{section}{\centering \Large \bfseries \scshape}
\setkomafont{subsection}{\large \bfseries \scshape}

\setcounter{secnumdepth}{-1}

\begin{document}
\setlength{\parskip}{0pt}

\section{Abstract}
\lipsum[1-2]

\vspace{0.5cm}

\begin{multicols}{2}
\section{Introduction}
    \lipsum[3]
\subsection{Some Intro Part}
    \lipsum[4-8]
\section{Results}
    \lipsum[3-4]
\begin{Figure2col}{12}
    \includegraphics[width=\linewidth]{example-image-a}
\end{Figure2col}
\begin{minipage}[][1\baselineskip][c]{\linewidth}
    \captionof{figure}[Figure A]{\textit{Figure A}}
\end{minipage}
\subsection{More Results}
    \lipsum[3-5]
\end{multicols}

\end{document}

已尝试的无效方案 #

• 在\section{Results}前添加\nointerlineskip
• 将章节标题字号改为\normalfont
• 在章节周围添加hrules和baselineskip

恳请提供有效建议！
