Mutation events
This feature is discouraged — Mutation events negatively impact performance and they were selected for removal from the web as part of Interop 2025.
Consider using MutationObserver instead.

Mutation events like DOMSubtreeModified, DOMNodeInserted, or DOMNodeRemoved fire when DOM changes occur.
