Why am I getting "event.returnValue is out of date ..." and how to fix it?

Question

On my website, when I F12 from the browser, I see an error / warning on the console (Chrome Dev Tools), "event.returnValue is deprecated. Instead, use the standard event.preventDefault () event."

However, I am looking for my project for "event.returnValue" and does not display instances of this line.

Assuming it's some kind of Microsoft or jQuery-written code that causes this, should I do something about this, and if so, then what?
