well, beforeInputEvent.preventDefault() got close to making the problems in contentEditable tractable... but when it comes to CJK it just shrugs and says "eh, good luck with composition".

On the subject of Cocoa, I can't even find the docs anymore for the low-level text shaping layers of the system. I've looked a couple of times because I want to re-implement some parts of those APIs. Everything seemed so well-designed, but now it's lost to the sands of time as Apple archives documents and Google search deteriorates. Alas.

EDIT: blessings! I found some of the docs for Cocoa's text layout system. Just look at this. If only we had this for the web, as a standard...

EDIT 2: Oh, Apple has a new text layout engine "TextKit 2". I haven't found any of the really nice technical illustrations or long-form guides for it. Instead, I'm watching this video: https://developer.apple.com/videos/play/wwdc2021/10061/
