AlternativeLayoutRule breaks LambdaCase

{-# LANGUAGE AlternativeLayoutRule #-}
{-# LANGUAGE LambdaCase            #-}

isOne :: Int -> Bool
isOne = \case 1 -> True
              _ -> False

main = return ()

$ ghc test-case
[1 of 1] Compiling Main             ( test-case.hs, test-case.o )

test-case.hs:5:15: error: parse error on input ‘1’

It compiles fine without the AlternativeLayoutRule extension.
