 | **delay** 🧪           | number             | undefined | false    | A number indicating the minimum delay in milliseconds between notifications from this observer for a given target. This must be set to at least `100` if `trackVisibility` is `true`.                                                                                                       |

If `skip` is set while `inView`, the current state will still be kept.                                                                                                               |
