I have working `.Rmd` files that contain latex syntax (rendering correctly). However, when I render using the `bookdown` package, I have experienced that the latex output is incorrect.
I went to check in the source (aka <https://bookdown.org/yihui/bookdown/markdown-syntax.html#math-expressions>) and I see that the render is not correct there either!

I see similar behavior for bookdown's `preview_chapter()` rendering but not for Rmarkdown knit of a toy example. I see similar behavior changing web browser.

**Is this something on my end? Are there updates I need to do?**
