What is the issue affecting?

Completion

Expected Behaviour

When using a defined class as the type for a parameter, the fields of that table should be offered as an autocompletion when calling the function.

For an example, using @alias works like so:

Actual Behaviour

No autocompletion is automatically offered when using @class as the type for a parameter. If you press CTRL + Space, you can make the completions appear, but they will not appear automatically.

Nothing is offered:

Until I press CTRL + Space:

Reproduction steps

1. Use the below code:

   ---@class Options
   ---@field page number
   ---@field active boolean
   
   ---@param opts Options
   local function acceptOptions(opts) end
   
   acceptOptions()
   

2. Move your cursor to line 9 (acceptOptions()) and place it between the parentheses
   
3. Enter { to start a table literal
4. No completions are offered
5. Press CTRL + Space and notice that the first 2 options are actually proper completions from the Options class. These should automatically be offered.

issue ではソースファイルもテストも指定されていません。まず、VS Code 拡張機能で提供されている Lua の再現コードを実行し、Options パラメーターに { を入力した後の補完の動作を追跡してください。@class フィールドが Ctrl+Space を押さなくても自動的に候補として表示されれば完了です。
