I sat by Steve when Writely joined Google. [Hi Steve!] I sat by the Google Page Creator team when they were a thing. Regardless of performance, it's a miracle that a WYSIWYG editor can be written on top of the DOM at all, let alone a performant one. They had to work multiple miracles a day just to get bulleted lists to work somewhat reliably. I have no doubt whatsoever that a Canvas-based editor can be faster and easier to maintain. I don't know how well it'll handle accessibility issues, though. I expect they'll have to do a lot of tedious work to get screen readers and the like to be happy.
