This MWE

----------------------------
\documentclass[12pt]{book}    
\usepackage{graphicx}
\usepackage{framed}    
\newcommand{\addImage}[4]
{
\begin{figure}
\centering
\begin{framed}
\includegraphics[width=#2\textwidth]{#3}\caption{#4}
\end{framed}
\end{figure}
}%
\usepackage{subcaption}    
\begin{document}    
\addImage{1}{0.3}{example-image-a}{Phase line diagram}    
\end{document}
-------------------

Compiled with lualatex, gives correct output, with caption below the image

enter image description here

But compiled with tex4ht using the command

make4ht -ulm default -a debug A.tex 'mathjax,htm'

gives this

enter image description here

Removing \usepackage{subcaption} from the code, now tex4ht gives correct
output

enter image description here

Is there a workaround for tex4ht?
