TH + out-of-scope variable panic

This silly program, which splices an out-of-scope variable, causes a panic:

{-# OPTIONS_GHC -fdefer-out-of-scope-variables #-}
{-# LANGUAGE TemplateHaskell #-}
module X where

import Language.Haskell.TH

a :: Code Q Int
a = [|| outOfScope ||]

{-# LANGUAGE TemplateHaskell #-}
module Y where

import X

b = $$(a)
