\mathcal doesn't render correctly on mobile browsers

[Raj Kane]

I have some \mathcal typesetting that renders as emojis on mobile browsers. Here is one example.

<p>We would like a dealer \(\mathcal{D}\) to generate shares \(\{s_i\}_1^n\) of a secret \(s\) and distribute them among \(n\) players \(\{\mathcal{P}_i\}_1^{n}\) obeying the following conditions.

And here is the result on a mobile browser (tested both Firefox and Safari) on iOS 15.5.

This issue is only present in mobile browsers. Everything renders as expected on desktop.

I include MathJax as

<script type="text/javascript" src="https://mathjax.rstudio.com/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>

What could be the cause?

The version of MathJax being used is v2.7.2, which is quite out of date.  The current version is 3.2.2, and the tests version 2 is 2.7.9, so you might try updating the version in use.

You might also try changing the output render in use.  The configuration file you are loading uses the original HTML-CSS output renderer, which is the oldest and most fragile one available in version 2.  You might try changing to the CHTML or SVG output renderer.
