equation rendering

[boyle]

Hi,
Thanks for a really sweet editor.

When I render lines with equations, I'm getting the equations replicating with each re-rendering as I edit the page.

test
- [ ] example $x$ what

after a rendering as I type, gives

in the preview window. Exiting and loading the file gives a correct render, but editing that line gives similar repeats.

Looks like maybe there's some search and replace for the update that is failing around the equations? Rest of the page, the lines without equations, render just fine.

ghostwriter 2.0.2
cmark version 0.29.0

Using the "cmark-gfm" in the Markdown Flavor for rendering in the Preview window.

This seems like a bug, but maybe I'm setting something up incorrectly?

Cheers!
