CommonHTML fails to use local bold fonts on Chrome

Created by: yutak

OS: Linux Chrome: 77.0.3865.10 (Official Build) Dev channel

I have MathJax fonts locally installed on my system (under /usr/share/fonts/mathjax/), and on that condition, CommonHTML seems to fail to use bold or italic fonts.

For instance, this:

<!DOCTYPE html>
<html>
<head>
<title>MathJax CHTML bold font test</title>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS_CHTML"></script>
</head>
<body>
<h1>MathJax CHTML bold font test</h1>
<p><code>\mathbf{ABCabc}</code> \( \mathbf{ABCabc} \)</p>
<p><code>\mathit{ABCabc}</code> \( \mathit{ABCabc} \)</p>
<p><code>\textbf{ABCabc}</code> \( \textbf{ABCabc} \)</p>
<p><code>\textit{ABCabc}</code> \( \textit{ABCabc} \)</p>
<p><code>\boldsymbol{ABCabc}</code> \( \boldsymbol{ABCabc} \)</p>
</body>
</html>

is rendered like this (see no bold or italic is applied):

MathJax CHTML bold font test - Google Chrome_020

Firefox renders this fine. HTML-CSS mode on Chrome is OK, too.

This seems to have something to do with a @font-face rule for a local font that has font-weight: bold; (or font-style: italic). This may be Chrome's regression.
