Warning Error | WordPress.org

Hi Support,

Warning Error found after inspecting a few pages (ERROR WARNING BELOW). Is this something that will resolve itself or will necessary action be needed for this? Thank you in advance for any feedback.

siteground-optimizer…6db4e45ef21bb.js:14 [Deprecation] Listener added for a synchronous ‘DOMNodeInserted’ DOM Mutation Event. This event type is deprecated (https://w3c.github.io/uievents/#legacy-event-types) and work is underway to remove it from this browser. Usage of this event listener will cause performance issues today, and represents a risk of future incompatibility. Consider using MutationObserver instead.
