while updating some past posts
here to take advantage of the new syntax highlighting i came across this odd bug.
When editing multiple posts on one page, after you save the n+1 changes, the last saved syntax highlighting changes get duplicated.
It doesn't duplicate into the database or anything, refresh shows it normal, but it was oddly confusing.
you can see
here that i changed them each in order, and after saving the next changes, ALL of the ones before duplicated, with each save. so by the time i saved the fourth post, the first post had quadruple rendering of the syntax highlighting.
