Looking closer at UAX 29 I think what this means is that a variation selector extends a grapheme cluster and does not cause a cluster break, because `extended grapheme cluster = [...] precore* core postcore*`... and `postcore` is a production for `[Extend ZWJ SpacingMark]` and `Extend` here are all codepoints which have the character property `Grapheme_Extend=yes`. So those sequences are covered. -- GitHub Notification of comment by drott Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/9291#issuecomment-1706230439 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
