About
Some months ago, Stack Exchange moved to highlight.js v11. One of the breaking changes of this version was the removal of the HTML auto-passthru, which SE uses to indicate addition/deletion in diffs (that is, nested spans in code elements). As a result, highlighting broke in code blocks for diffs.
The bug was reported on MSO and MSE. A week later, a "hotfix" was pushed which has been out for... 2 months! Essentially, it disabled highlight.js entirely on the pages where there were diffs (revisions and suggested edits).
What is this?
This is a highlight.js plugin. The idea as well as a large part of the code have been taken from this GitHub issue.
