Generic.Rep doesn't derive inner records #2911

Is this expected behaviour?

 data A = A { b :: { c :: Array String } }

The Generic.Rep representation is:

(Constructor "A"
   (Rec
      (Field "b"
         { c :: Array String
         }
      )
   )
)

I would have expected the inner record to result in Rec (Field "c" ... and so on.
