Problem properly selecting parts of code chunks (in browser)

[RemPsyc]

I've made a detailed post (with screenshots and sample code) on stackoverflow, and someone commented that he could confirm the problem, thought it was a bug, and that I should post it here. But basically I'm not able to select part of text from code chunks using common browsers such as Chrome, Edge, or Explorer, though I don't have this issue when not using prettydoc.

Yeah, I can reproduce this. This is the first time I realize this issue as I typically use Firefox, which sees no problem in selecting the code.

Let me take a look and see where it comes from.

I believe this is related to jgm/pandoc#4278. The problem is that some versions of Pandoc add a pointer-events: none; attribute to the code lines, making the text unselectable.

I have made a patch to prettydoc and the new version is on the way to CRAN.
