I use `QWebEngineView` to convert Markdown to HTML and render the math formula via MathJax. All the content are inside a `<div id="placeholder">`. Then I use `document.getElementById("placeholder").innerHTML` to get the HTML content, which contains the converted Markdown content and rendered MathJax output. At last, I output the HTML content to a HTML file.

However, when I open the exported HTML file via Chrome, the formulas lose the CSS styles like [this demo](http://js.do/tamlok/export_mathjax).

So any idea to make the formulas in order?

I have tried to add MathJax script to the exported HTML but the formulas will disappear.

Thanks!
