Fixed
- Security: Upgraded DOMPurify from 3.4.0 to 3.4.11, fixing CVE-2026-49458, CVE-2026-49459, and CVE-2026-49978. #GH-186
- Security: Fixed the namespace tracker to pop all stale scopes instead of just one, closing an
iframe srcdocXSS vector reachable through namespace confusion. (CVE-2026-47760) - Security: Rewrote the sanitization hook to avoid a DOMPurify 3.4.9+ parentless-guard throw that could abort the sanitize walk when elements were pre-detached by the hook.
