 ## Implementation notes
 
-N/A
+* 1️⃣ Screenshot feature is **failing** because of missing [`structuredClone` API](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone#browser_compatibility) on Node.js 16. Since the problem is **inside** `puppeteer` ([issue](https://github.com/puppeteer/puppeteer/issues/11004)), the feature is turned off for this version.
