Sorry, I assumed the text in "Reproduction" would not be formatted. The first language block should obviously be "js" and the second "r".

Also I should mention that shiki appears not to be to blame, as R code is properly highlighted here: https://codesandbox.io/s/shiki-next-js-forked-jc1yuc?file=/pages/index.js
