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

Since ---@alias annotations can stand for more than just ---@class annotations, I vote for not implementing this feature and closing as won't fix.

What is the alias being used for? Why not just use the class's name?
