函数提示信息和函数实际信息不一致

```lua
---@class A
local m = {}

---@overload fun(msgId:number, buffer:string)
---@overload fun(msgId:number)
---@param msgId number
---@param buffer string
---@param len number
function m:SendMsg(msgId, buffer, len) end

---@class B
local n = {}

function n:test()
    local t = m
    t:SendMsg(1, "")
end
```

n:test中，t:SendMsg的鼠标提示和m:SendMsg的实际信息不一致
