Guard against duplicate custom element registration#136
Merged
DanWebb merged 1 commit intoMar 21, 2026
Conversation
Adds safeCustomElement decorator that checks customElements.get() before defining, preventing NotSupportedError when the same element is imported multiple times or when multiple versions of Evergreen are loaded on the same page. A console.warn is emitted when a duplicate registration is detected, making version conflicts visible rather than silent. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
