Could not deduce `RecordFromJSON'` and `RecordToPairs` in `aeson-2.2.0.0`

I have the following code
```hs
{-# LANGUAGE DeriveGeneric #-}

import Data.Aeson
import GHC.Generics

data Item f a = Item { root :: a, children :: f a } deriving Generic1

instance FromJSON1 f => FromJSON1 (Item f) where liftParseJSON = genericLiftParseJSON defaultOptions
instance ToJSON1 f => ToJSON1 (Item f) where liftToJSON = genericLiftToJSON defaultOptions
instance (FromJSON1 f, FromJSON a) => FromJSON (Item f a) where parseJSON = parseJSON1
instance (ToJSON1 f, ToJSON a) => ToJSON (Item f a) where toJSON = toJSON1

data Content f a = Content { items :: f (Item f a) } deriving Generic1

instance (Functor f, FromJSON1 f) => FromJSON1 (Content f) where liftParseJSON = genericLiftParseJSON defaultOptions
instance (Functor f, ToJSON1 f) => ToJSON1 (Content f) where liftToJSON = genericLiftToJSON defaultOptions
instance (Functor f, FromJSON1 f, FromJSON a) => FromJSON (Content f a) where parseJSON = parseJSON1
instance (Functor f, ToJSON1 f, ToJSON a) => ToJSON (Content f a) where toJSON = toJSON1

main :: IO ()
main = return ()
```

With `aeson-2.1.2.1`, this code works perfectly fine. With `aeson-2.2.0.0`, I get the following errors:
```

I looked at the changelog, and while there have apparently been some changes to the handling of Generics related to omitted fields, I did not find anything that would indicate that my situation should no longer work. Is this a regression or am I doing something wrong?
