Hi 👋
Thank you for this handy utility!
We found there was an event listener and a bunch of timing events that were not cleaned up on component destruction, which led to their accumulation over time, causing memory leaks. This PR clears them just before the component unmounts. You can see the difference in the count of memory leaks as detected by Memlab.
