Reproduction steps

Maybe I'm doing something wrong, but it seems to have worked before

---@class Test
---@field ID integer
local Test = {};

---@param id integer
---@return Test
function Test:new(id)
    return setmetatable({ ID = id }, { __index = self });
end

---@type table <integer, table<integer, number>>
local tab = {
    [1] = { 1.0, 2.1, 3.2 },
    [2] = { 4.0, 5.1, 6.2 },
    [3] = { 7.0, 8.1, 9.2 }
}

---@generic T
---@param test table<integer, T>
---@return table<Test, T>
local function convert2Test(test)
    local t = {};
    for k, v in pairs(test) do
        t[Test:new(k)] = v;
    end
    return t;
end

local newTab = convert2Test(tab);

for k, v in pairs(newTab) do
    print(k, v); -- ok! k and v detected
end

local test = Test:new(3);
local info = newTab[test];

if info then
    for k, v in pairs(info) do
        print(k, v); -- oops! k and v not detected
    end
end

从 issue 中的 Lua 复现开始，比较预期和实际截图中的推断类型。调查用于 tab 的嵌套表类型，以及通过 convert2Test 返回的值。当内层表的键和值类型在最终的 pairs 循环中被推断出来时，即表示完成。
