@see annotaton duplicates documentation when using with @class

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Annotations

Expected Behaviour

I'm trying to add some @see tags to my @class

Actual Behaviour

When hovering class in editor, displayed documentation is printed twice.

Reproduction steps

Here is basic code sample. Hovering or typing class1 causes issue with displayed documentation

--- some class dock
---
---@class C2
local class2 = {}

--- another class dock here
---
---@see C2
---@class C1
local class1 = {}

---@type C1
local class1_instance = class1

从 issue 中提供的 Lua 复现开始，比较 C1 在有和没有 @see C2 注解时的 hover 结果。由于没有指定 repository 文件或测试，因此请定位 language server 使用的注解和类文档处理逻辑，然后验证 C1 的文档只显示一次，同时 @see 引用仍然可用。
