Description
func =
[ abc x y
| _ <- aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
-- comment
, x <- bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
, y <- ccccccccccccccccccccccccccccccccccc
]
Each roundtrip through brittany will decrease the indentation of the comment.
Currently I cannot think of an easy fix on brittany's end for this because the ghc-exactprint interface is a bit unfortunate for this usecase. I have raised https://github.com/alanz/ghc-exactprint/issues/53.

Research direction
Start by reproducing the Haskell snippet through brittany and review the linked ghc-exactprint issue #53, which describes the relevant interface limitation. Done means repeated formatting roundtrips no longer decrease the indentation of the comment.
