Generic attribute constraint doesn't work

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

Empieza reproduciendo el problema con el ejemplo ClassA/AddChild y colocando el cursor sobre el parámetro item. Sigue el manejo de las restricciones genéricas utilizado por la comprobación de tipos y la finalización, y verifica después que el resultado del hover exponga los campos Name y Thing de ClassA para T y siga indicando correctamente el tipo restringido.
