Adding ---@class breaks auto completion

使用報告中的 Lua 範例在 Visual Studio Code 擴充功能中重現此問題，比較有和沒有 ---@class err.Player 註解時的補全結果。追蹤類別註解的補全處理，並驗證存在該註解時會出現 p:set_position()、p.x、p.y 和 p.happy。

What is the issue affecting?

Completion

Expected Behaviour

I'm running into an issue where adding the ---@class annotation to a local variable seems to break auto completion. It should appear correctly even if the ---@class is affixed to a local variable.

Actual Behaviour

The autocomplete variables and functions are not appearing.

Reproduction steps

Here is a simple example of creating a new player class with the issue.

-- Here is a simple example of creating a new player class with the issue
-- Uncommenting the line below *breaks* the autocompletion for p.new()
-- ---@class err.Player
local Player = {}
Player.__index = Player

local function mixin_xy(o)
    o.x = 0
    o.y = 0

    o.set_position = function(self, x, y)
        self.x = x
        self.y = y
    end

    return o
end

function Player.new()
    local self = {}
    self.happy = true
    self = mixin_xy(self)

    return setmetatable(self, Player)
end

local p = Player.new()
-- `p:set_position(), p.x, p.y, p.happy` no longer showing in auto complete if `---@class err.Player` is uncommented

When ---@class err.Player is uncommented, and above local Player = {}:

When ---@class err.Player is removed or commented:

The above image is the expected behaviour. However, when ---@class err.Player is added above local Player = {} it no longer works.
