Does the stages inherit the materializer strategy?

ActorMaterializerSettingsApp.scala

package streams

import akka.actor.ActorSystem
import akka.stream.ActorAttributes.SupervisionStrategy
import akka.stream.Supervision.Resume
import akka.stream._
import akka.stream.scaladsl.Source
import akka.stream.stage.{GraphStage, GraphStageLogic}

object ActorMaterializerSettingsApp extends App {

  implicit val system = ActorSystem()
  implicit val mat = ActorMaterializer(
    ActorMaterializerSettings(system).withSupervisionStrategy(Supervision.restartingDecider: Supervision.Decider)
  )

  class Test extends GraphStage[SourceShape[String]] {
    val out = Outlet[String]("ba")
    val shape = SourceShape.of(out)
    override def createLogic(inheritedAttributes: Attributes): GraphStageLogic = new GraphStageLogic(shape) {
      println(inheritedAttributes.get[SupervisionStrategy] eq Supervision.restartingDecider)
    }
  }


  Source.fromGraph(new Test).runForeach(println)


  system.terminate()

}
