In tex4ht, when doing


\centering
\includegraphics[width=0.6\textwidth]{example-image-a}

The image comes out centered. But when adding fbox, the images no longer is
centered

\centering
\fbox{\includegraphics[width=0.6\textwidth]{example-image-a}}

I was not sure if this is by design or if it should remain centered. It does
remain centered in pdf. Here is MWE

---------------------------
\documentclass{article}
\usepackage{amsmath} 
\usepackage{graphicx}
\usepackage{hyperref}

\begin{document}

\begin{figure}
\centering
\includegraphics[width=0.6\textwidth]{example-image-a}
\caption{Phase plot}
\end{figure}

\end{document}
----------------------

Compiled using

make4ht -ulm default -a debug  foo.tex 'mathjax,htm'
gives image centered ok.

(btw, I never figured out how to make TL testimages show up as the true image
on my system with tex4ht. They always show as PIC, but using actual image I
have, same problem show up).

Now when adding \fbox{....} around the includegraphics here is the result

         enter image description here

But in PDF, it remains centered even when adding \fbox
