Equals sign within LaTex block causes previous line to be rendered in Table Of Contents

[christopherMills]

What's the problem

Seems to be a parsing error.

When using LaTex, even when clearly demarcated by $$ on new lines, snippets of that LaTex block end up in the auto-generated ToC if (and seemingly only if) there is a = on its own line. The line that ends up in the ToC is the line immediately before the = in the LaTex block.

What's the expected result

LaTex expressions should not be picked up in the ToC regardless of what's inside them since they are demarcated by $$.

How to reproduce

Write a LaTex block that has a = on its own line. Generate the ToC. The line above the = will be inserted into the ToC.

Other information

I am attaching a test MarkDown file that clearly reproduces this bug.
