### Reproduction steps

Is it possible to implement this annotation method?

```lua
---@diagnostic disable: missing-return

function CreateFramePool(...) end
function CreateFrame(...) end

---@template
---@class ObjectPoolMixin
---@field creationFunc fun(self: self)
---@field resetterFunc fun(self: self, object: T)
---@field activeObjects T[]
---@field inactiveObjects T[]
---@field hashinactiveObjects T[]
---@field numActiveObjects integer
ObjectPoolMixin = {};

---@template
---@param creationFunc fun(self: T)
---@param resetterFunc fun(self: self, object: T)
function ObjectPoolMixin:OnLoad(creationFunc, resetterFunc) end

---@template
---@return T object
---@return boolean isNew
function ObjectPoolMixin:Acquire() end

---@template
---@class FramePoolMixin: ObjectPoolMixin
---@field parent T1
FramePoolMixin = {};

---@class Button1
---@field a table
---@field b integer
local Button1 = {};

---@class Button2
---@field c string
---@field d number
local Button2 = {};

---@class Frame1
local frame1 = CreateFrame("Frame");

---@class Frame2
local frame2 = CreateFrame("Frame");

---@class Frame1Pool: FramePoolMixin
frame1.pool = CreateFramePool("Button", frame1);

---@class Frame2Pool: FramePoolMixin
frame2.pool = CreateFramePool("Button", frame2);

local parent1 = frame1.pool.parent; -- Should be defined as Frame1
local parent2 = frame2.pool.parent; -- Should be defined as Frame2

local activeObjects1 = frame1.pool.activeObjects; -- Should be defined as Button1[]
local activeObjects2 = frame2.pool.activeObjects; -- Should be defined as Button2[]

local button1 = activeObjects1[1]; -- Should be defined as Button1 or nil
local button2 = activeObjects2[1]; -- Should be defined as Button2 or nil

```

Start with the Lua reproduction in the issue, focusing on the @template and @class inheritance annotations and the expected types for parent and activeObjects. Trace how the language server currently interprets these annotations, then verify that the example preserves both template parameters and resolves the shown fields as Frame1/Frame2 and Button1[]/Button2[].
