ParallelListComp leads to syntactically invalid result

[StefanFehrenbach]

This Haskell file compiles just fine with ghc 8.10.

{-# LANGUAGE ParallelListComp #-}

         main = undefined
         b = undefined
         c = undefined
         d = undefined
         e = undefined

         a      =  [ b
                            |  c
                            | d <- e
                           ]

But running brittany 0.13.1.1 on it causes it to print an error: ERROR: brittany pretty printer returned syntactically invalid result. Running with --output-on-errors produces this output

{-# LANGUAGE ParallelListComp #-}

main = undefined
b = undefined
c = undefined
d = undefined
e = undefined

a = [ b | c d <- e ]
