* Fix MM-57406: prevent IPv6 hex segments from parsing as emoji Add word-boundary lookbehind and lookahead to EMOJI_PATTERN so a :name: token is only matched when neither side abuts an alphanumeric/underscore. Without this, hex runs in IPv6 addresses (e.g. :beef: in 2001:18:1:beef::/64) were tokenized and rendered as custom emoji. The new semantics align with the server parser at server/public/shared/markdown/emoji.go. Bump the webapp babel safari target from 16.2 to 16.4 since regex lookbehind is a syntax feature and is not lowered by @babel/preset-env. The actual supported minimum is well above 16.4, so the previous target was stale. Add regression tests for the IPv6 case and guardrail tests for back-to-back, paren-wrapped, and punctuation-terminated emoji. Update the existing asdf🐐asdf💨asdf test to reflect the new (server-aligned) semantics. * Dedupe word-char class in EMOJI_PATTERN Use \w in the lookarounds and inside the name matcher ([\w+-]) so the word-char set is expressed once instead of being repeated as two slightly different literal character classes. Same set, same semantics; addresses review feedback on PR #36541. --------- Co-authored-by: Miguel de la Cruz <miguel@ctrlz.es>
