Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

It looks like on StackExchange sites that have MathJax enabled, certain placements of $ characters inside code blocks can prevent the code block from ending.

Here's an example post where this has happened. Please see the longest code block: the middle should be text, but it is rendered as code.

I managed to come up with a minimal example. The following markdown,

    $ this is code

this is text


renders like this:

$ this is code

this is text


(i.e. the middle text line appears as code).

The improved Markdown/LaTeX separator now handles this case. I've made an edit to the post to force rebuilding the HTML – and remove the sentence noting that something is broken :) – and it now looks as expected.

Your minimal example now works correctly as well.

There's another note about the broken rendering at the beginning of the post. I removed that one as well. Thanks! :-) – Szabolcs May 31 '12 at 13:43
There are some problems again with $ signs and code blocks. Try this on a MathJax enabled site: The second code line will have extra indentation. Again, this comes up on Mathematica.SE in practice, because Mathematica tends to use $ signs (for example, in this post, if the second, empty, line of the code block is removed.) – Szabolcs Dec 8 '12 at 17:18
