> And my point is simply that google docs is explicitly designed to prevent any of these sort of issues from being noticable to the user. I’ve demonstrated one place where it very obviously failed at this goal, and I know enough about variation in shaping to confidently state that others do exist, though the most obvious are almost entirely historical. But there are variations that can change glyph advance, which will affect layout. They use the browser’s shaping, so they’re subject to its quirks. In order to obtain absolutely consistent layout, they’d need to do the shaping themselves, but they have chosen not to do that (and I think they’re right not to). Google Docs has clearly been pushing for non-pagination in more recent times, and paragraph layout largely doesn’t matter once you’re not fussing about pagination. They reimplemented breaking paragraphs into lines, but gained literally nothing thereby in terms of actual functionality or behaviour, since the browser offers absolutely everything they wanted from it, and they still rely on the browser for the shaping.
