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)

Riproduci il problema in LuaLS con le annotazioni NumberTable e FirstElement fornite, usando Neovim su Linux come descritto. Confronta il tipo inferito di t[1] con il caso diretto number[] e le varianti di table. Il lavoro è completato quando le annotazioni generiche e di tabella ereditate identificano sistematicamente l’elemento come number.
