cdn version duplicates math symbols?

[yosun]

Trying to use in a website from cdn (just modifying this boilerplate documentation example), but not sure why this is doubling by showing both the frac version and each num/dem twice?

var text = "Hi, this is a line of text. $\\frac{\\alpha}{2}$"

Make sure latex.js, base.js and katex.css files are loaded on page
