I previously submitted a bug on what I thought was a code bug, but which turned out to be (partly) a mistake on my part and was canceled:
https://list.orgmode.org/878r2b4dpy.fsf@localhost/T/#m48b7ea939117f241069fafbcf3726587837f3e70 But there is still a doc bug: since the default value of `org-html-head-include-scripts' was changed to `nil' in Org 9.5, the functionality described in the `Literal Examples' section of the manual is no longer enabled by default. The attached patch adds a footnote to describe how to enable that functionality. Thanks to user @JeanPierre on Emacs SE for the original question and the push for the doc patch: https://emacs.stackexchange.com/questions/80783/org-mode-export-to-html-onmouseover-highlighting-of-referenced-code-lines
