missing fonts - Githubissues

I have installed dvisvgm using sudo dnf install dvisvgm (version 3.0.4).

Let math.tex contains (it is based on the sphinx.ext.imgmath template preview.tex_t)

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{anyfontsize}
\usepackage{bm}
\pagestyle{empty}

\usepackage{bbm}
\usepackage{xcolor}
\usepackage{mathtools}

\AtBeginDvi{\special{color rgb 0.08984375 0.3125 0.91796875}}

\newcommand\cc[1]{\texttt{#1}}

\usepackage[active,tightpage,dvips]{preview}

\begin{document}
\begin{preview}
\fontsize{14}{17}\selectfont $\beta = \frac{\cc{leads}_h}{\cc{leads}}$
\end{preview}
\end{document}

When I use

tectonic --outfmt xdv math.tex
dvisvgm --no-fonts math.xdv

the stdout of dvisvgm is

pre-processing DVI file (format version 7)

and math.svg is "broken". If I then dnf install texlive-fontspec, all is as expected:

pre-processing DVI file (format version 7)
processing page 1
  computing extents based on data set by preview package (version 13.1)

  output written to math.svg

I presume that tectonic has already downloaded the required fonts but dvisvgm is looking for texlive -installed fonts. Is it possible for dvisvgm to use tectonic fonts (maybe it is just a matter of providing the right path)?
