Equations in html vignettes do not render properly in Rstudio browser

[jthaman]

System details

RStudio Edition : Desktop
RStudio Version : 1.0.153
OS Version      : Ubuntu 17.10
R Version       :  3.4.2

Steps to reproduce the problem

install.packages("ciTools")
library(ciTools)
??ciTools

Then click on the first vignette in the Rstudio browser window.

Describe the problem in detail

I'm having an issue viewing equations in the Rstudio browser. When I load my package vignette in Firefox, MathJax does it's thing and it looks great, but when I open my vignette in Rstudio, the equations are rendered as raw latex.

Describe the behavior you expected

Expecting the latex equations to render correctly. Is this a limitation of Rstudio or a problem with my package? My vignettes are using html_vignette output

@jthaman Can you provide a screenshot of what you're seeing? I tried reproducing it using the steps you provided, but the Vignettes are rendering OK for me. Also, you might consider upgrading to the current release of RStudio Desktop, available at https://www.rstudio.com/products/rstudio/download/ if possible.

Sure, here is a pic of what I'm seeing in the Rstudio browser. This pic is on Windows 7 with the latest R and Rstudio (I just downloaded them tonight). It's the same as what I see on my ubuntu computer. I have also tried this on a Mac and observe the same result. What does it look like on your computer?

I see a current failure on RStudio Desktop 1.2.358 on Ubuntu 16.04.3 (also RStudio Desktop 1.1.423). The rest of the environments I checked work in 1.2.35x, the latest development/test daily builds. So, I'll mark this is an issue to review for the current development cycle. Thank you for raising this!

Ubuntu 16.04: 1.1.423 & 1.2.358
