Expected Behaviour

If I have an @alias for a class, I expect it to be usable in inheritance for other classes, ex. @class MyNewClass : MyAlias

Actual Behaviour

The inheritance triggers undefined-doc-class diagnostic although the alias can still be ctrl+clicked to go to its source.

Reproduction steps

Snippet that reproduces the issue:

---@class MyClass

---@alias MyAlias MyClass

-- Will trigger undefined-doc-class, though MyAlias can be ctrl+clicked to go to source.
---@class MyNewClass : MyAlias

從提供的 Lua 重現開始，追蹤類別宣告繼承時如何處理 @alias 的解析。完成標準是 MyNewClass : MyAlias 不再產生 undefined-doc-class，同時仍可從該別名導覽至其原始碼。
