When defining global variable using `---@class _G` + `---@field`, no autocompletion in `_G.*` for those injected fields

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?

Completion

Expected Behaviour

The _G class is defined in extension's basic.lua, representing the global vairable. I expected the following should merge the defined fields into the global variable.

---@class _G
---@field player_min integer
---@field player_max integer

print(p--[[should have autocompletion]])
print(_G.p--[[should have autocompletion]])

Actual Behaviour

LuaLs recognized the injected field in the hover preview of _G, however no autocompletion for those fields are provided, unless I write _G._G.*.

---@class _G
---@field player_min integer
---@field player_max integer

print(p--[[no autocompletion]])
print(_G.p--[[no autocompletion]])
print(_G._G.p--[[!!! has autocompletion !!!]])

Reproduction steps

Use the code snippet provided above.

Additional Notes

LuaLS actually recognized the injected fields in the hover preview of _G, just the autocompletion is not working as expected.

Meanwhile the workaround is the use ---@type annotation for global variable. However as discussed here, unless the global variable is of table type, otherwise any default value assigned to it will be misleading as the global variable may not be a const.

Tái hiện hành vi hoàn thành mã trong tiện ích mở rộng Visual Studio Code bằng đoạn mã Lua được cung cấp, sau đó kiểm tra định nghĩa basic.lua cho _G và đường dẫn hoàn thành mã. Được xem là hoàn tất khi các trường được khai báo bằng @field trên _G xuất hiện trong cả hoàn thành mã toàn cục và hoàn thành mã _G., mà không yêu cầu _G._G..
