make4ht is creating unnecessary span sibling tags in abstract. The following example shows this behavior:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\begin{document}
\begin{abstract}
\lipsum[1-1]
\end{abstract}
\lipsum[1-1]
\end{document}
The resulting HTML is:
<!DOCTYPE html>
<html xml:lang='en-US' lang='en-US'>
<head> <title></title>
<meta charset='utf-8' />
<meta content='TeX4ht (https://tug.org/tex4ht/)' name='generator' />
<meta content='width=device-width,initial-scale=1' name='viewport' />
<link type='text/css' rel='stylesheet' href='test.css' />
<meta content='test.tex' name='src' />
</head><body>
<section role='doc-abstract' class='abstract'>
<div class='center'>
<!-- l. 10 --><p class='noindent'>
</p><!-- l. 10 --><p class='noindent'><span class='rm-lmbx-9'>Abstract</span></p></div>

Is there a fix to prevent this behavior? Unfortunately HTML Tidy has no merge option for sibling tags.
