Wrong formatting of records being parts of data families?

[michalrus]

E.g. this fragment was autoformatted:

instance GM 'Practice where
  data MatchConfig 'Practice = MatchConfig'Practice{teamSize ::
                                                  Int,
                                                  ladder :: Ladder}
                               deriving (Generic, Show, Eq)

I would rather expect something like this to happen:

instance GM 'Practice where
  data MatchConfig 'Practice = MatchConfig'Practice
    { teamSize :: Int
    , ladder :: Ladder }

… as it would happen, were this a regular top-level record.
