Class inheriting a generic class with specified type not recognized as inherited class (assign-type-mismatch)

Empieza con la reproducción en Lua del issue y pásala por la comprobación de tipos de la extensión de Visual Studio Code para observar el diagnóstico assign-type-mismatch. Rastrea el manejo de la herencia de clases genéricas y, a continuación, verifica que Test_Class1 se acepta tanto como Test_Generic como como Test_Base, incluido el caso de herencia transitiva, mientras el comportamiento existente de Test_Class2 sigue siendo válido.

Type Checking

Expected Behaviour

The type of a class inheriting a generic class (when specifying the type) should be recognized as the same type as the class it inherits.
If that generic class inherits another class, that should also be recognized.
As such, the following code should have no problems.

--- @class Test_Base
--- @field Str_A string
local Test_Base = {}

--- @generic T
--- @class Test_Generic<T> : Test_Base
--- @field Gen_T T
local Test_Generic = {}

--- @class Test_Class : Test_Generic<string>
local Test_Class = {}

--- @type Test_Base[]
local testArray = {
    Test_Base,
    Test_Generic,
    Test_Class,
}

Actual Behaviour

"Test_Class" isn't recognized as either "Test_Generic" or "Test_Base", therefore showing as an "assign-type-mismatch" error.

However, inheriting the generic class without specifying the type is completely fine.

--- @class Test_Base
--- @field Str_A string
local Test_Base = {}

--- @generic T
--- @class Test_Generic<T> : Test_Base
--- @field Gen_T T
local Test_Generic = {}

--- @class Test_Class : Test_Generic
local Test_Class = {}

--- @type Test_Base[]
local testArray = {
    Test_Base,
    Test_Generic,
    Test_Class,
}

Reproduction steps

--- @class Test_Base
--- @field Str_A string
local Test_Base = {}

--- @generic T
--- @class Test_Generic<T> : Test_Base
--- @field Gen_T T
local Test_Generic = {}

--- @class Test_Class1 : Test_Generic<string>
local Test_Class1 = {}

--- @class Test_Class2 : Test_Generic
local Test_Class2 = {}

--- @type Test_Base[]
local testArray = {
    Test_Base,
    Test_Generic,
    Test_Class1,
    Test_Class2,
}

Additional Notes

This problem showed up after the release of version 3.17.0

I know that the implementation of generics is complicated, and I've already found a workaround for my use-case by casting the inheriting classes to the type of the underlying base class. But that may not work for others.
