Table literals aren't properly checked for field injections and missing fields

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Linux

Type Checking

Expected Behaviour

I'd expect tables created in the return statement to check for missing fields, and those created outside of them to check for injected fields.

Actual Behaviour

There are no warnings emitted for the attached code.

Reproduction steps

Code to reproduce the issue:

---@class Tile
---@field name string

local Tile = {}

---@return Tile
function Tile.new()
	---@type Tile
	local d = {
		name = 'abc',
		f = 10 -- No warning when a field is being injected
	}

	return {
		f = 10 -- No warning even though there's a missing field and a field is being injected
	}
end

Note that it won't produce any warnings, regardless of configuration (as far as I can tell).

Additional Notes

No response

Log File

No response

Start with the Lua type-checking path for the reproduced Tile example and inspect how table literals in return statements and typed locals are validated. Reproduce the issue in the VS Code extension, then verify that injected fields produce warnings and that the returned table reports both the missing name field and the extra f field.
