Unexpected behaviour when using zio with fs2

FS2TaskInterop.scala

import fs2.Stream
import zio.interop.catz._
import zio.{ Runtime, Task }

object FS2TaskInterop extends App {
  val runtime = Runtime.default

  val nonStream = Task(123).map(_ => BigDecimal("16:19:25.242056065Z"))
  val stream    = Stream.eval(nonStream)

  // prints the `zio.Exit.Failure`
  println(runtime.unsafeRun(nonStream.run))
  // throws a `FiberFailure`
  println(runtime.unsafeRun(stream.attempt.compile.toList))
}
