Parsing confused by type-level string (Symbol)

[jchia]

The following code snippet is parsed incorrectly. The last two lines for main are completely unhighlighted in the vscode editor. The problem goes away if "of" is changed to "f". I'm running language-haskell 2.4.0 on vscode 1.19.0 with ghc 8.2.2.

{-# LANGUAGE DataKinds, FlexibleInstances, KindSignatures, MultiParamTypeClasses, FunctionalDependencies #-}

import GHC.TypeLits

data Label (l :: Symbol) = Get

class Has a l b | a l -> b where
  from :: a -> Label l -> b

data Point = Point Int Int deriving Show

instance Has Point "of" Int where from (Point x _) _ = x

example = from (Point 1 2) (Get :: Label "of")

main :: IO ()
main = undefined

Also I am noticing that attaching the kind signature to the l type parameter makes the data keyword not work.
