Expected Behaviour

1. Define a generic base class Foo with a method function which returns the generic type
2. Inherit from the base class and specify the generic type
3. Use the method and expect the specified generic type on the output

---@class Foo<T>
---@field myValue T
local base = {}

---@return T
function base:get()
	return self.myValue
end

---@type Foo<number>
local ex1 = base --Use class directly
---@class Example2 : Foo<string>
local ex2 = ex1 --Start with a version with generic type specified
---@class Example3 : Foo<boolean>
local ex3 = base --Start with a version without the generic type specified

local I 	= ex1.myValue 	--Correct: number
local a 	= ex1:get() 	--Correct: number
local II 	= ex2.myValue 	--Correct: string
local b 	= ex2:get() 	--Correct: string
local III 	= ex3.myValue 	--Correct: boolean
local c 	= ex3:get() 	--Correct: boolean

Actual Behaviour

Attempting to expand the parent class directly displays a warning, (Example 3) but using a variable with specified type does not (Example 2).
The method defined in the parent class fails to infer the generic type from the child classes

---@class Foo<T>
---@field myValue T
local base = {}

---@return T
function base:get()
	return self.myValue
end

---@type Foo<number>
local ex1 = base
---@class Example2 : Foo<string>
local ex2 = ex1
---@class Example3 : Foo<boolean>
local ex3 = base --Cannot assign 'Foo' to 'Example3'

local I 	= ex1.myValue 	--Correct: number
local a 	= ex1:get() 	--Correct: number
local II 	= ex2.myValue 	--Correct: string
local b 	= ex2:get() 	--Incorrect: T
local III 	= ex3.myValue 	--Correct: boolean
local c 	= ex3:get() 	--Incorrect: T

Reproduction steps

1. Define a generic base class with a method function which returns the generic type
2. Inherit from the base class and specify the generic type
3. Use the method and expect the specified generic type on the output
