Cannot inherit generic classes (including tables)

Hello, I apologize for bringing yet another generics issue as I know it takes time for it to be made solid... Thanks for looking into my problem. I use the following code to extend the number[] class, but then the elements are not marked as numbers for a non literal object.

---@class NumberTable: number[]

---@param t NumberTable
---@return number|nil
function FirstElement(t)
  local n = t[1] -- marked as unknown
  return n
end

---@param t number[]
---@return number|nil
function FirstElementBis(t)
  local n = t[1] -- marked as number
  return n
end

I would expect t[1] to be marked as number. I also tried replacing number[] with table<number> and table<number, number> without success. Thank you!

(I use LuaLS on Neovim on Linux)

按照描述，在 Linux 上使用 Neovim，结合提供的 NumberTable 和 FirstElement 注解，在 LuaLS 中复现该问题。将 t[1] 的推断类型与直接使用 number[] 的情况以及 table 的变体进行比较。当继承的泛型和表注解能够一致地将元素识别为 number 时，即表示完成。
