"unsatisfiable constraint" error puts solver into an inconsistent state about kiwi.js

That's great investigative work Gavin, thank you for filling this! I don't have any bandwidth to address this problem any time soon, but if you provide a PR I will try to verify and merge it quickly.
Cheers!

Sure thing. I should say, that since I did not understand the Simplex algorithm very well to begin with, I ended up reading the literature and writing my own basic implementation in order to learn it. I am currently working through the Cassowary papers and am quite impressed how you got so much into such a compact program. However, I'm not 100% sure I'm going to come out of this yak shave.

Well, frankly you probably already know more than me in this area 😅
This project was originally written by Chris Colbert and based on the algorithms of the kiwi C++ constraint solver (https://github.com/nucleic/kiwi). I found it useful and used it in https://github.com/IjzerenHein/autolayout.js and after a couple years of laying dormant decide to publish it, as I felt it could be useful to other folks as well. That being said, I don't really actively use kiwi.js in any of my work right now. Feel free to post a PR though, I'll review it 👍
