Use Hexo's renderer to render the preview

This is a nice plugin for posting blog articles. But I've some concerns. At the beginning, I am using some markdown editor to write articles, and find it is not good because there are some extended markdown syntax or other plugins (example: mathjax, diagram) which my editor may not support.

But, when I tried hexo-admin, it also cannot support these plugin, and I can confirm that if I open the post article in browser directly, it works (it shows my math equations, my diagrams). Can the "preview" of hexo-admin preview the actual final results (same with what you see in browser directly)? Or I've missed anything? If not supported, I do not see a reason to use hexo-admin instead of other markdown editors. Any idea?

Thanks,

No files or tests are named in the issue. Start by tracing how hexo-admin generates the preview and how Hexo renders posts; done means the preview matches the browser-rendered article, including extended Markdown features such as MathJax and diagrams.
