change default MathJax config from TeX-MML-AM_HTMLorMML to TeX-MML-AM_CHTML

The math in my HTML doc wasn't rendering correctly in Chrome (on MacOS), even though it worked on Safari and on Chrome in iOS.
This is what it looked like:

I noticed that by default, this line is added to the HTML file for MathJax:

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.9/MathJax.js?config=TeX-MML-AM_HTMLorMML"></script>

When changing TeX-MML-AM_HTMLorMML to TeX-MML-AM_CHTML the output looked as expected on all browsers that I've tested:

and CommonHTML also seems to be the recommended choice by MathJax themselves. Is there any reason for not switching to TeX-MML-AM_CHTML as the default config?
