tex2jax: "}" as the end of math mode

Created by: sstenchlak

It doesn't work when you use "}" as the end of math mode if the equation contains braces. E.g.

tex2jax: { inlineMath: [ ["\\equation{","}"] ] } some text \equation{\frac{1}{n} > 0} some text

I'm guessing the problem is that https://github.com/mathjax/MathJax/blob/419b0a6eee7eefc0f85e47f7d4f8227ec28b8e57/unpacked/extensions/tex2jax.js#L239 is not evaluated when search.end === "}".
