在多列环境中使用 floatflt 将 itemize 环绕在图形周围 - 图形不显示

我正在制作一张海报，使用 a0poster 样式，我试图将 itemize 列表包裹在图形周围。我尝试了 wrapfigure 包，但我发现它不适用于 itemize 列表，所以我尝试了 floatflt，它应该可以很好地与列表配合使用（前提是您使用 \fltitem）。我的 MWE 如下：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{floatflt}
\usepackage{multicol}
\usepackage{lipsum}
\usepackage[margin=2cm]{geometry}

\setlength\parindent{0pt}

\begin{document}
\lipsum[1]
\begin{multicols}{2} 

\section{Introduction}
\lipsum[2-3]

\begin{floatingfigure}[r]{0.5\columnwidth}
\centering
\includegraphics[width=0.48\columnwidth]{universe.jpg}
\caption{very very very very very very very very very very very very very very very very long caption}
\label{fig:example}
\end{floatingfigure}

\begin{itemize}
    \fltitem{one very very very very very long text}
    \fltitem{two very very very very very long text}
    \fltitem{three very very very very very long text}
\end{itemize}
\lipsum[4-7]

\end{multicols}
\end{document}

结果是（请注意列表旁边没有图像）：

以下内容基于https://tex.stackexchange.com/a/417571/117050但对其进行了大量扩展。它定义了宏：

  • \InsertListR[<correction>]{<skip>}{<contents>}参数<correction>是所使用的校正因子insbox（使用它来扩展受影响的行数）、<skip>插入前要跳过的行数以及<contents>要插入的框。
  • \wrapitem用于启动第一个项目，之后使用\InsertListR
  • \contitem使用后的另一个项目\InsertListR也应受到影响。它需要一个可选参数来指定受影响的行数（默认为 100）
  • \EndInsert\InsertListR手动停止或任何其他宏的效果insbox。它还会开始一个新段落。如果要抑制缩进，您可以使用带星号的版本。

\begin{document}

\begin{multicols}{0}
  \section{Introduction}
  \blindduck[-5]
  \begin{itemize}
    \wrapitem
    \InsertListR{0}
      {%
        \parbox{.48\columnwidth}
          {%
            \includegraphics[width=.48\columnwidth]{example-image-duck}%

    \contitem three very very very very very long text
  \end{itemize}
  \EndInsert*
  \blindduck[1-5]
\end{multicols}
\end{document}

结果：

在此处输入图片描述

编辑：更合理的默认值\contitem。默认情况下，此版本执行insbox与计算受影响行数相同的计算。如果您对结果不满意，可以明确给出数字。它还将的默认值更改\InsertListR为合理的0（空的默认参数将与 1 相同，这不是预期的行为insbox）。

出于我还不理解的原因， 的效果在环境\InsertListR之后的下一个新段落结束itemize。因此，我添加了一个宏\MoreInsert，它将当前段落中应受影响的行数作为参数（仅在当前段落中，另一个新段落会结束其效果）。
