I've been following this 20 year old Firefox bug as I came up against it once: https://bugzilla.mozilla.org/show_bug.cgi?id=4522 - I just got a bugzilla alert because a 14 year old bug it depended on has now been fixed.
This bug has been fixed using a language that never even existed when it was submitted (Rust).
Just thought it was interesting.
What is interesting about this bug, except that it is 14 years old?
It almost got a summer job and a learners' permit. Sad day. :'(
