vscode does not list server-provided completion items.

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

vscode displays the enum

Actual Behaviour

vscode shows no completion available, despite server response.

Reproduction steps

---@alias Option string | "AAA" | "BBB" | "CCC"
---@param x Option[]
local function f(x)
end

f({"|"}) <- trigger completion

Additional Notes

No response

Log File

No response

首先，使用复现步骤中的 Lua 代码片段在 Visual Studio Code Extension 中复现补全问题，然后检查 Completion 区域的服务器响应是如何呈现的。当 VS Code 在标记的触发位置显示枚举值 AAA、BBB 和 CCC 时，即表示完成。
