在 make4ht 中，无法使用 \ref 链接到 \phantomsection

我的代码：

\documentclass{article}
\usepackage{hyperref}
\begin{document}
Top of document

\section{Section heading}
Top of section

. \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\
. \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\

\phantomsection
\label{fooref}
We want to create a reference to this part of the document.

. \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\
. \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\ . \\

Go to reference \ref{fooref}.

Bottom of document.
\end{document}

如果我使用 PDF 查看器创建文档pdflatex foo.tex && pdflatex foo.tex并打开它foo.pdf，单击创建的引用\ref{fooref}就会带我到当前的\phantomsection位置\label{fooref}。

但是，如果我使用 创建文档make4ht foo.tex并用浏览器打开foo.html，单击创建的引用\ref{fooref}会将我带到页面顶部。这是一个错误吗？有办法解决这个问题吗？

尝试这个配置文件：

\Preamble{xhtml}

\makeatletter
\def\phantomsection{%
 \Hy@GlobalStepCount\Hy@linkcounter
 \xdef\@currentHref{likesection.\the\Hy@linkcounter}%
 \Hy@raisedlink{\hyper@anchorstart{\@currentHref}\hyper@anchorend}%
 \edef\@currentlabel{\the\Hy@linkcounter}%
 \AnchorLabel%
}
\makeatother
\begin{document}
\EndPreamble

\phantomesection它重新定义了TeX4ht 使用的默认定义，它\label通过以下几行添加了支持：

\edef\@currentlabel{\the\Hy@linkcounter}%
\AnchorLabel%

第一行定义文本中将使用的引用的值，第二行将链接目的地插入文本中。

这是最终的 HTML 代码：

<!-- l. 5 --><p class='noindent'>Top of document
</p>
   <h3 class='sectionHead' id='section-heading'><span class='titlemark'>1   </span> <a id='x1-10001'></a>Section heading</h3>
<!-- l. 8 --><p class='noindent'>Top of section

</p><!-- l. 13 --><p class='indent'>   <a id='likesection.1'></a> <a id='x1-1001x1'></a> We want to create a reference to this part of the document.

</p><!-- l. 24 --><p class='indent'>   Go to reference <a href='#x1-1001x1'>1<!-- tex4ht:ref: fooref  --></a>.
</p><!-- l. 26 --><p class='indent'>   Bottom of document. </p>

如您所见，<a id='x1-1001x1'></a>插入到的位置\phantomsection，并<a href='#x1-1001x1'>1</a>指向该位置。
