disposing of a `createRoot` nested inside a `createEffect`?

I am creating a nested effect, like:

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

Will the root be automatically disposed when the scope of the first

createEffect

createEffect

createEffect

createEffect gets disposed? How can I inspect that?
