Expected Behaviour

如题，下面的 stringBox.combine(text, "true") 应该不会显示任何诊断问题：

---@generic T
---@class Box<T>
---@field storedValue T
---@field combine2 fun(first: T, second: T): T
local Box = {}

---@param first T
---@param second T
---@return T
function Box.combine(first, second) end

---@type Box<string>
local stringBox

local text = "123"
local r1 = stringBox.combine(text, "true")
local r2 = stringBox.combine2(text, "true")

Actual Behaviour

stringBox.combine(text, "true") 的两个参数均被诊断为：

Cannot assign `string` to parameter `T`.
- `string` cannot match `T`
- Type `string` cannot match `T`

而用@field声明的同类型函数combine2却能正常识别实参

Reproduction steps
