Generic attribute constraint doesn't work

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Type Checking, Completion

Expected Behaviour

When using the @generic attribute on a method (---@generic T : ClassA) and I have a parameter as type T (---@param item T The item), when I hover over that item parameter I would expect it to list all fields in ClassA

Actual Behaviour

It doesn't list the constrained type's fields. I just see the hover tooltip say: (parameter) item: <T:ClassA>, but none of ClassA's fields are shown

Reproduction steps

Use this code:

---@class ClassA
---@field Name string
---@field Thing string
local ClassA = { Name = "name here", Thing = "thingy"}

---Adds an item
---@generic T: ClassA
---@param item T the Item
function ClassA:AddChild(item)
end

And hover over the item parameter on AddChild, and it won't show any of the fields of ClassA

Commencez par reproduire le problème avec l’exemple ClassA/AddChild et en survolant le paramètre item. Suivez ensuite la gestion des contraintes génériques utilisée par la vérification de types et la complétion, puis vérifiez que le résultat du survol expose les champs Name et Thing de ClassA pour T et signale toujours correctement le type contraint.
