run() scope

[DrSensor]

run(() => {
  const pid = seInterval(() => {
    console.log("print every 1s")
  }, 1 * s)
  return () => clearInterval(pid)
}, when?: string)

Those that are wrapped in run() scope will run every time (not just once) current <render-scope> is in view and stop (call returned function) when out of view.
