duplicate-set-field diagnostic when assigning a function to a table field

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

No diagnostic warning on assignment because the variable has been 'cleared'.

Actual Behaviour

The two info.func assignments that are "= function" get a Duplicate field 'func' (duplicate-set-field) diagnostic.
The info.func assignment "= l1" does not.
Scope depth does not seem to impact the diagnostic - within the same function.

Assignments to other fields that are string, integer, etc do not get the diagnostic.
FYI - the ".func" is expected in a library I cannot change.

Reproduction steps

local function l1()
end
local function f1()
local info = {};
do
info = {};
info.notCheckable = true
info.func = function()
-- any code
end
end
info = {};
info.notCheckable = true
info.func = function()
-- any code
end
info = {};
info.notCheckable = true
info.func = l1
end

从复现步骤和 Diagnostics/Syntax Checking 子系统中的 duplicate-set-field 诊断开始。比较所提供 Lua 代码片段中的三个 info.func 赋值，然后找到该诊断现有的测试或实现。当两个内联函数赋值不再产生所报告的警告，同时 l1 赋值和其他 duplicate-field 检查仍有覆盖时，即表示完成。
