missing-fields ignores fields set post-assignment

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?

Diagnostics/Syntax Checking

Expected Behaviour

Assigning a table to a variable with @type annotation and filling out the class's fields and functions afterwards should not trigger missing-fields.

Actual Behaviour

A missing-fields diagnostic is triggered despite fields being set after the initial assignment of the variable yet before the variable is used for anything.

Reproduction steps

Small script that replicates the issue:

---@class MyInterface
---@field DoAction fun()

---@type MyInterface
local inst = {}

-- Does not remove `missing-fields` diagnostic
inst.DoAction = function() end

missing-fields will trigger on inst.

從 issue 中的 Lua 重現開始，追蹤一個欄位在初始化後才被指派的具型別表格之缺少欄位診斷。在 Windows 上的 Visual Studio Code 擴充功能中確認該行為；當變數使用前，指派後的欄位不再產生缺少欄位診斷時，即表示完成。
