@ryanmcalister I have committed. Here, try this.

1. I have dropped codeblock support. The reason is that it conflicts with codeSyntaxHighlight plugin in tui.editor 3.x. If the formula drawn in codeblock with Katex's Plugin, codeSyntaxHighlight overwrites it and breaks it.

2. character escape feature tui.editor 3.x seems to have a feature to escape (_). If you save a file before enclosing it in $$, it seems that (_) is converted to (\_). Latex strings enclosed in $$ previously do not seem to be converted even after reloading.

hmm, I'm still seeing the escaping of _ when I reload the note or switch between markdown.
