研究方向: The issue is in the TypeScript DOM type definitions, likely in lib.dom.d.ts. The fix involves making cloneNode generic so that it returns the subtype. Check the issue comments for proposed solutions and consider using overloads or conditional types. No linked PRs exist, so this is a fresh opportunity for a first time contributor.
