Interesting, I hadn’t come across that particular issue, though it seems obvious now (I know about those ugly old fullwidth fonts). And I’m guessing that quite incidentally -apple-system and BlinkMacSystemFont are unlikely to be affected. I’ll need to reconsider my recommendation—though I will note that I’ve not generally used system-ui anyway, just considered it acceptable. I wonder if it’s time to lobby browsers to update their default sans-serif fonts, as they have updated their monospaces over the last few years (except for Firefox on Windows). The whole ui-sans-serif/ui-serif/ui-monospace thing is a bit of a crock. (And I wonder if I stand any chance of getting the 13px monospace default size killed. That thing is such an utterly obsolete nuisance—though of course removing it from monospace doesn’t remove the concept, which is used in fonts of various languages.)
