Does this gem support server-side rendering?

There is a gap before MathJax comes into play. So user sees initial TeX string before MathJax starts to render TeX into something beautiful. For now I just hide elements with visibility: hidden that might contain TeX but this feels like a hack and not user-friendly.

As far as I know, it is possible to render TeX with Mathjax server-side, just not with this gem (needs to be run in server side JS)

You could always try to save the already rendered HTML/whatever and display that.
