Yes, the error appears to be in the pkgload::load_rd_macros() function 
here: 
https://github.com/r-lib/pkgload/blob/1b1adc39628671f2ea4256f0bebcdb76e1f89f45/R/dev-help.r#L47.

It doesn't look at the DESCRIPTION file to see if there's an RdMacros entry.

My guess is that 'Preview' uses tools::Rd2HTML() and that indeed won't automatically understand macros coming from mathjaxr (or any add-on package for that matter). This would be an issue to raise with the RStudio folks then.
