This option was introduced out of caution as a way for developers to opt out of the new behavior in v18 which scheduled change detection even when events happened outside the NgZone. After monitoring the results post-release, we have determined that this feature is working as desired and do not believe it should ever be disabled by setting this option to `true`. This option was deprecated in v18.2, less than 3 months after it was introduced in v18. We do not really expect it to be used. BREAKING CHANGE: `ignoreChangesOutsideZone` is no longer available as an option for configuring ZoneJS change detection behavior.
