`@overload` does not cooperate with `@class` when adding overloads to an inherited class method

How are you using the lua-language-server?

Completion

Expected Behaviour

Adding an overload to a function inherited from another class should result in both the parent class' overloads and the new overload being suggested as autocomplete and hover tooltip entries.

Actual Behaviour

Adding an overload to a function inherited from another class makes that overload the only one that is recognized for the current class.

Reproduction steps

---@meta

---@class ParentClass
ParentClass = {}

---@param arg string
---@return unknown
---@overload fun(self, arg: "bar"): boolean
function ParentClass:foo(arg) end

---@class ChildClass : ParentClass
---@field foo fun(self, arg: "baz"): number
ChildClass = {}

ChildClass:foo(--[[Should suggest both "bar" and "baz", but only suggests "baz" and "bar" raises a param-type-mismatch]])

Redefining the function and adding an @overload there yields the same result.

Additional Notes

Having some way to mark a function redefinition as an overload (with strict checking that it does exist in the class defined as inherited from) would probably help solve this issue.

Comece com o comportamento das anotações e do preenchimento automático de Lua mostrado na reprodução, concentrando-se em como a herança de @class e as declarações @overload são tratadas. Reproduza o caso no NeoVim e verifique se o preenchimento automático e o hover exibem tanto o overload "bar" herdado quanto o overload "baz" filho, sem incompatibilidade no tipo do parâmetro.
