---comment
---@param value any
---@return "boolean"|"function"|"nil"|"number"|"string"|"table"|"userdata"|"thread"
local function myAwesomeFunction(value)
return type(value)
end
```

### Actual Behaviour

### Log File

_No response_

使用 Lua 範例在 Visual Studio Code 擴充功能中重現此問題，並從 `---` 觸發自動完成。將產生的 `---@return` 註解與預期行為中顯示的完整 union 進行比較；當較大的回傳型別不再使用 `...(+3)` 縮寫時，即表示完成。
