   That's really odd, but I'm able to replicate it. Just to be clear, the text you're trying to load contains the TOC as a code block, correct?

   Correct. TOC in a fenced code block.

   It must have something to do with syntax highlighting. The issue goes away when I disable that feature in Style preferences. I'll have to look into it. It doesn't make sense that that code block would cause any issues, so it might take me a bit to figure out the cause.

   Ok, yes, this is hanging when highlight.js is invoked. Complete mystery as to why at this point, but looking into it. In the meantime, if you go into Settings->Style and next to the Syntax Highlighting checkbox you'll see "only if language specified." Checking that will avoid running syntax highlighting on this particular block (or any block where you don't add a language after the code fence). This assumes you do want syntax highlighting on other code blocks, otherwise you could just disable completely.

   I'm trying to track down why this is happening today, will update if I figure it out.

   Solved the issue just by updating Highlight.js. Not sure what was hanging it, but will publish a release soon that will solve the issue.
