MathJax breaks my indentation

Question

Seems like there is a bug, that breaks my indentation.

See

In third code section of Create New C++ Class
In first code section of Code Generator Generator
multiple times in the code section of https://codereview.stackexchange.com/a/84104/ (Perl syntax naturally includes both \$ and $$).

This occurs on both block delimiters and inline delimiters. Live minimal test case:

$$
b0rked
$$

and

\$
b0rked
\$

In the Markdown source, all lines are vertically aligned, not additionally indented

Hmmm... I can reproduce it, and do not understand why it is broken..... — rolfl♦, Feb 15 '15 at 15:07
reproduced on our dev environment, it's mathjax related, happens when we're baking a post's markdown to html, looking into it — m0sa♦, Feb 16 '15 at 15:49
@m0sa has there been any progress on this problem? I was baffled why my code – even in the editor preview – had this random extra indentation. That kind of sucks for a site that's about clean code, which involves proper formatting. — amon, Mar 16 '15 at 8:07
@amon I looked into it, turned out to be a deep rabbit hole requiring at major refactoring of MarkdownSharp (we'd need to make the pipeline extensible, so we could inject stuff before DoCodeBlocks in RunBlockGamut - currently all the processing happens before we ever hit MarkdownSharp, but we'd need to leverage it's block processing) — m0sa♦, Mar 16 '15 at 11:49

This seems to happen because of the above line having two $ in a row.

static std::string TOKEN_LINEDUMP("$$
    static std::string TOKEN_INDENTNEXT("$$>");

Removing the second $ on the first line causes it to be shown normal:

static std::string TOKEN_LINEDUMP("$
static std::string TOKEN_INDENTNEXT("$$>");

Further investigation is needed.

\$\begingroup\$ is this related to mathjax?? \$\endgroup\$ – Vogel612♦ Feb 15 '15 at 15:50

\$\begingroup\$ Actually, removing any of the $ will stop the indentation. This does make it look like a MathJax issue. \$\endgroup\$ – Jamal♦ Feb 16 '15 at 1:40

\$\begingroup\$ FYI, this is not due to MathJax itself since MathJax stops parsing at HTML elements, so it won't touch <span class="str">"$$>"</span> etc. However, it could have something to do with the way StackExchange's editor isolates LaTeX-input from the Markdown processor. \$\endgroup\$ – Peter Krautzberger Feb 17 '15 at 13:25
\$\begingroup\$ Could we not have some  magic comment to switch off MathJax on top of a code block? \$\endgroup\$ – Mathieu Guindon Oct 17 '15 at 23:22
