docsify-katex breaks sidebar expansion and mermaid support

[biker2000on]

When I add docsify-katex to the index.html page, the sidebar no longer expands to show the headers. It also does no longer converts the headers to links. Also, when added, mermaid code blocks no longer render, but are displayed in a code block instead.

Thanks for your feedback, and now it has been fixed.
See this demo.

To use it now, just change your js cdn to latest version on GitHub:

<script src="//cdn.jsdelivr.net/gh/upupming/docsify-katex/dist/docsify-katex.js"></script>

You can give a star to docsify-katex star if it helps ~
