define a class bug?

[ZhangMingHe2333]

     ---@class Student
local Student = {
	name = nil,
	age = nil,
}
---@type Student
local sd = {}
local age = sd.age

this way can work at v2.6.8 and it did't work after update to 3.X

I have some issue here:

---@class Foo
---@field f number
---@type fun(self: Foo, ...): Foo
local Foo = setmetatable({}, {
    __call = function(self)
        return self
    end
})

function Foo.new()
end

function Foo:doSomething()
    return self.f -- Undefined field `f`. 
end
