Goto autocompletion doesn't respect Editor: Insert Spaces setting

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?

Completion

Expected Behaviour

As can be seen in the images below, the autocompletion of goto continue will indent the ::continue:: line with four spaces, while my settings have Editor: insert spaces unchecked, which means it should insert a tab character instead.

Actual Behaviour

Note: in these images, the tab character is rendered as an arrow, while spaces are rendered as dots.

Reproduction steps

1. In VSCode, set your Editor: Insert Spaces setting to false
2. Try the following code:

local arr = {}

for k,v in pairs(arr) do
	if type(k) == "string" then
		goto continue
	end
    ::continue::
end

3. When you start typing goto continue, and select the popup, you'll get the four spaces indentation instead of tab on the ::continue:: line.

Commencez par reproduire le comportement de complétion de goto dans l’extension VS Code avec Editor: Insert Spaces désactivé et le snippet Lua fourni, puis suivez le chemin de complétion. C’est terminé lorsque la sélection de goto continue indente le label avec un caractère de tabulation plutôt qu’avec des espaces lorsque ce paramètre est désactivé.
