CONSOLE WARNING: Listener added for a 'DOMNodeInserted' mutation event. This event type is deprecated, and will be removed from this browser VERY soon. Usage of this event listener will cause performance issues today, and represents a large risk of imminent site breakage. Consider using MutationObserver instead. See https://chromestatus.com/feature/5083947249172480 for more information.
This test verifies that a mutation event that removes inserted nodes from the document doesn't crash upon the insertion of a new node into the document.
PASS: You didn't crash.
