What's the problem

when using

### blah: $\text{QMA}_{c,s}$

the "c,s" is weirdly uppercased, which is not what I want!

This happens in slide mode when you "customize slides" with a theme.

This wasn't a problem during June 2023! Something changed since then.

It's because the white theme of revealjs has default to do uppercase styling for all headings. You can use style tag to overwrite it or use other theme.

<style>
    .reveal h1, .reveal h2, .reveal h3, .reveal h4, .reveal h5, .reveal h6 {
        text-transform: none;
    }
</style>

This wasn't the behavior I wanted, but the following worked for me:

<style>
    .reveal h1 .mathjax, 
    .reveal h2 .mathjax, 
    .reveal h3 .mathjax, 
    .reveal h4 .mathjax, 
    .reveal h5 .mathjax, 
    .reveal h6 .mathjax {
        text-transform: none;
    }
</style>
