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

Beginne mit den Reproduktionsschritten und der Diagnose duplicate-set-field im Subsystem Diagnostics/Syntax Checking. Vergleiche die drei info.func-Zuweisungen im bereitgestellten Lua-Snippet und ermittle anschließend die vorhandenen Tests oder die Implementierung der Diagnose. Erledigt ist die Aufgabe, wenn die beiden Inline-Funktionszuweisungen nicht mehr die gemeldete Warnung erzeugen, während die l1-Zuweisung und andere Prüfungen auf duplicate-field weiterhin abgedeckt sind.
