Is JSX Preview safe?

Low risk

JSX Preview loads preview-engine libraries from esm.sh and can add Tailwind's CDN while rendering JSX.

When you preview JSX or TSX, the sandboxed engine imports React, Babel, and UI libraries from esm.sh, then compiles and renders the code inside the preview page. If Tailwind support is enabled, the preview page also loads a script from cdn.tailwindcss.com.
