Listener added for a synchronous 'DOMNodeInserted' DOM Mutation Event deprecated

[jalil2024]

Listener added for a synchronous 'DOMNodeInserted' DOM Mutation Event. This event type is deprecated (https://w3c.github.io/uievents/#legacy-event-types) and work is underway to remove it from browsers. Usage of this event listener will cause performance issues today, and represents a risk of future incompatibility. Consider using MutationObserver instead.

Possibly related to this: In Firefox found warning "Use of Mutation Events is deprecated. Use MutationObserver instead". It points to datepicker-widget.js:46

    document.addEventListener('DOMNodeInserted', function (event) {

This event (DOMNodeInserted) which of the Mutation Events is used to detect changes in the DOM tree but most browsers are of the motion that it slows down performance hence the use of it is discourage. Chrome for instance has stated that it would be disabling these event feature in June. It was suggested that MutationObserver be used instead

Seems like this is a duplicate of #115 and was already fixed. For Google Chrome the removal of those mutation events is announced for July 2024, so the end is near ;-). Will we have a new release before? Thanks
