Mathjax blocks are not highlighted correctly in 4.2.2

[randy3k]

The math equations inside $$ $$ are not highlighted.

By interestingly, \[ \] is highlighted but not rendered.

The version of the notebook server is 4.2.2 and is running on:
Python 3.5.2 | packaged by conda-forge | (default, Jul 26 2016, 01:32:08)
[GCC 4.8.2 20140120 (Red Hat 4.8.2-15)]

This is probably related to differences between the code mirror lexer and the underlying JSON parser:

Code mirror probably expects standard LaTeX formatting, which \[…\] is(technically you aren't supposed to use $$…$$ if you're writing LaTeX as it is a classic TeX command that has nonstandard spacing… which I'm guessing has been explicitly excluded from activating highlighting for that reason.)

However js sees \[ as just escaping the [ so it won't render, but \\[ … \\]will. I guess this would qualify as a bug but I don't know if the place to fix it is on the Jupyter end… it might be I'm just not sure.

If I am correct, Mathjax uses $$ ... $$ in default.

#1757 fixes an issue regarding CodeMirror config for text (markdown and raw) cells. I've tested and syntax highlighting is working for math inside of $ brackets but still not for $$ brackets. The question is: was highlighting of math inside of $$ brackets ever supported? @minrk Do you know?
