Memory leak when using WriterT

I'm experiencing a memory leak on the latest v3.2.7 when using an effect type that includes WriterT. I've put together a repository to reproduce the issue and to demonstrate that it doesn't happen when using plain IO -- https://github.com/mrdziuban/fs2-WriterT-memory

Here's a minimized example to reproduce the issue:

import cats.data.WriterT
import cats.effect.IO
import cats.effect.unsafe.implicits.global
import fs2.Stream

val longString = "a" * (1024 * 1024)

Stream[WriterT[IO, Unit, *], Unit](()).repeat.map(_ => longString).compile.drain.run.unsafeRunSync()

Also in a scastie here: https://scastie.scala-lang.org/mrdziuban/o8jjvkgOQVOwYnJ1A831dQ/4

Start with the minimized Scala example in the issue and compare its WriterT behavior with plain IO, then inspect the linked reproduction repository and Scastie example. Done means the repeating stream no longer retains the large mapped strings or exhibits the reported memory leak when run with WriterT.
