Break in loop makes variable go out of scope early?

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Linux

What is the issue affecting?

Type Checking

Expected Behaviour

I was trying to fetch a table that could be within a number of tables. Leaving early if it was found

I wanted that locally scoped variable to be the same type after the loop as before it

Actual Behaviour

Only for my variable scoped outside the loop to be unknown after it.
In an attempt to band-aid what I originally luals choking a little, I tried casting it. Only to find it was in fact unaware it even existed.

Reproduction steps

As minimal I can get the code to be and reproduce it:

---@type {[any]:A}
local T

function F()
    ---@class A
    local a

    for _, i in pairs{} do
        a = T[1]
        if a then break end
    end

    -- See it complain the `a` variable
    ---@cast a A
end

Additional Notes

No response

Log File

service.log

Start with the minimal Lua reproduction in the issue and inspect type-checking behavior around the local a, the for loop, and break. Done means a retains its A type after the loop and the ---@cast a A line is no longer reported as unknown; add a regression test using this reproduction.
