CONSOLE WARNING: Listener added for a synchronous 'DOMSubtreeModified' 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.
This tests calls to setInnerHTML, setInnerText, and setOuterHTML to see what kind of DOM modifications they cause. The calls are optimized to not do any work in cases where the DOM would not change at all.
