It's probably to do with the snark - intentional or otherwise - in your leading "Whoops!" - it comes across as "hey, everyone, I'm really clever because I found a flaw" which a) several other people found anyway b) you didn't actually report accurately; as others point out, the 'wobbling' is the positioning algorithm still running, nothing to do with scrolling c) is an edge-case; no matter what your claim that "200 points aren't a lot", most timelines I've ever seen online have had nowhere near 200 points. It's also painfully obvious before you even begin that 200 labels won't fit at all sensibly in the given width, so nobody using this library would actually make such a blundering mistake.
