Error cascade for TLKSs without accompanying declarations

If I write this:

{-# LANGUAGE TopLevelKindSignatures #-}
module Bug where

type Wat :: ()

I get a surprising amount of errors as a result:

[1 of 1] Compiling Bug              ( ../Bug.hs, ../Bug.o )

../Bug.hs:4:1: error:
    Top-level kind signature for a type previously declared:
      type Wat :: ()
    (The kind signature must be given where ‘Wat’ is declared.)
  |
4 | type Wat :: ()
  | ^^^^^^^^^^^

../Bug.hs:4:6: error:
    The top-level kind signature for ‘Wat’
      lacks an accompanying binding
  |
4 | type Wat :: ()
  |      ^^^

The first error message seems misguided, as Wat wasn't previously declared before. I would expect only to receive the second error message about lacking an accompanying binding. Well, I suppose it should say "declaration" instead of a "binding", but that's another matter.
