Error "Undefined field" on _G if global is declared by Lua.diagnostics.globals

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Linux

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

local extract0 = bit32 and bit32.extract -- Lua 5.2/Lua 5.3 in compatibility mode
local extract = _G.bit32 and _G.bit32.extract -- Lua 5.2/Lua 5.3 in compatibility mode

Expected: No error

Actual Behaviour

Error on 2nd line:

(global) _G.bit32: unknown
Undefined field bit32.Lua Diagnostics.(undefined-field)

Reproduction steps

1. Add 'bit32' to globals;
2. Errors on 1st line disappeared; but errors on 2nd line persists.

Additional Notes

sumneko.lua-3.6.18-linux-x64

Real global variables does not trigger errors. Only Lua.diagnostics.globals items lead to errors.

Additional question: how to mute errors for this pattern?

if _G.bit then -- LuaJIT
    local shl, shr, band = _G.bit.lshift, _G.bit.rshift, _G.bit.band
...
end

@diagnostic disable: mute too much, but @diagnostic disable-line: mute too little.

Lua.diagnostics.globals と bit32 を使用して Visual Studio Code 拡張機能の診断問題を再現し、直接アクセスと _G.bit32 によるアクセスを比較します。設定された globals に対する診断処理を追跡します。_G.bit32 が未定義フィールドを報告しなくなり、無関係な未定義フィールドの診断と行レベルの抑制動作が維持されていれば完了です。
