Can't use mathematical typesetting (MathJax)

[drinkdhmo]

There is no option under the Extras menu to enable mathematical typesetting

For those who come to this bug and wonder why it's not available (or why many of drawio's features aren't included)...

The TLDR answer is: mxgraph's reference graph editor does not have the mathematical typesetting feature.

Although this project includes drawio it its name, it is not based on drawio. Rather it is based on mxgraph's grapheditor reference implementation of an editor that uses mxgraph's library. Drawio, like this project, is also a derivative of this reference implementation with significant customization. It's quite confusing how it all gets mashed in to final product.
