textDocument/definition has incorrect results in some contexts

[wu4]

local record TestType
  test_value: boolean

  metamethod __call: function(self: TestType): boolean
end

local TestType_mt: metatable<TestType>
--[[
  trying textDocument/definition on `TestType_mt` attempts to go to the definition for `metatable` in stdlib.d.tl
  - should always go to `local TestType_mt`
]]
TestType_mt = {
  __call = function(self: TestType): boolean
    --[[
      trying textDocument/definition on `self` fails (No LSP Definitions found)
      - should go to `self` in the function parameters

      trying textDocument/definition on `test_value` fails (No LSP Definitions found)
      - should go to `test_value` within `local record TestType`
    ]]
    return self.test_value
  end
}

--[[
  trying textDocument/definition on `a` goes to `local record TestType`
  - should go to itself as this is the definition

  trying textDocument/definition on `test_value` fails (No LSP Definitions found)
  - should either go to itself or to `test_value` within `local record TestType`
]]
local a: TestType = setmetatable({test_value = true}, TestType_mt)

--[[
  trying textDocument/definition on `a` goes to `local record TestType`
  - should probably go to __call in the metatable, but could also reasonably go to `local a`
]]
a()

Yeah, I'm able to replicate, this is some odd behaviour. Thanks for reporting!
