The following code fails with java.lang.Error: Defect in zio.ZEnvironment: Could not find ErrorExample::Context inside ZEnvironment(Any -> Context(42))

import tofu.WithRun
import tofu.zioInstances.implicits.zioTofuWithRunImplicit
import zio._

object ZIOWithRunError extends ZIOAppDefault {
  case class Context(x: Int)

  val app: RIO[Context, Unit] = ZIO.service[Context].flatMap(Console.printLine(_))

  override def run: ZIO[Any with ZIOAppArgs with Scope, Any, Any] =
    WithRun[RIO[Context, *], Task, Context].runContext(app)(Context(42))
}

Based on the error message, it seems like Context's tag is not used to build ZEnvironment when using WithRun instance, resulting in ZIO being unable to find Context instance in the environment.
