使用 LaTeX 的默认计数器机制交叉引用 SVG 图形内的项目

这是基于上一个问题我试图使用该svg包来引用 SVG 绘图内的项目，但从未收到完整的答案。

我尝试采用不同的方法，即使用基本的 LaTeX 计数器机制，如上文所述这里并创建/引用我自己的计数器。

以下是得出的结论：

\documentclass{article}

\usepackage{svg}

\newcounter{svgelem}[figure]
\newcommand{\labelsvgelem}[1]{\thesvgelem\label{#1}}

\begin{document}
    \begin{figure}
        \refstepcounter{svgelem}
        \includesvg{example.svg}
    \end{figure}
   
Referring to \ref{test-rect} as rectangle and \ref{test-circ} as circle 

\end{document}

对于以下 SVG 文件：

我编译如下：

latexmk -lualatex --shell-escape test.tex

不幸的是我得到的是：

如您所见，图中第一个元素的标签确实出现了（尽管很小），但第二个元素的标签却没有出现，我不知道为什么。

我怎样才能让它工作？ 有没有更干净的替代方案？

答案1

标签被椭圆的线遮住了：

% !TeX program = txs:///arara
% arara: pdflatex: {synctex: on, interaction: nonstopmode, shell: yes}
