Is [data-type="equation"] math Font-Size broken?

[DokusLab]

Is the Font-Size for equations set by stump, @/components/readers/epub/EpubJsReader or somewhere else?

Because it seems to be broken, or am I mistaken?
div[data-type="equation"] math {
font-size: calc(0.35em + 1vw);
}

Seems to be way off for Desktop, where 1vw would be 113.6px for 1080p width.

Stump applies minimal styling overrides here, I'm sure it's possible that something in there is messing it up. Maybe that 'font-size': 'unset' bit, if I had to guess.

I don't have any books with equations in them to test this with though. Would you mind emailing me this one? If there are reasons (e.g. copyright) which disallow that, no worries! I can try to find a more open one to debug the issue
