Issue Type: Bug

Steps to reproduce

• Create a TypeScript file.
• Create a type alias with some name, and write a JSDoc comment for it.
• For types and functions:
  • Create a function with the same name, write a different JSDoc comment.
  • Hover over the type name. You will see the function’s comment, followed by the type’s comment.
  • Hover over the function. You will only see the function’s comment.
• For types and values:
  • Create a value identifier with the same name, write a different JSDoc comment.
  • Hover over the type name. You will see the type’s comment, followed by the value’s comment.
  • Hover over the value identifier. You will see the type’s comment, followed by the value’s comment.

Bắt đầu bằng cách tái tạo tệp TypeScript tham chiếu và so sánh kết quả quickinfo cho cặp kiểu/giá trị với cặp kiểu/hàm. Truy vết quá trình xử lý quickinfo và JSDoc liên quan đến các hover đó, sau đó bổ sung độ bao phủ hồi quy cho các chú thích tooltip dự kiến và xác minh rằng mỗi khai báo hiển thị tài liệu phù hợp.
