jQuery UI 1.13.0 changed the logic attaching the `_untrackClassesElement` listener in the `_classes` widget method; one of the side effects was calling `this._on` for each node that needed the listener. That caused a severe performance degradation for large comboboxes as each `_on` jQuery UI call causes a jQuery `add` call that calls Sizzle's `uniqueSort` underneath. Instead, collect the nodes that need the listener and then, outside of the loop, create a jQuery object out of them and attach the listener once. That's still slower than the jQuery 1.12 version but only slightly: 936 ms to 1.03s on a very large list on a recent MacBook Pro, compared to ~30 seconds before this patch.
