After filtering, when clicking any element in the filtered list, the first one is always selected

This can be consistently reproduced.
It only happens when selecting an element right after changing the filter.
If you press any keyboard key or click outside the box before selecting, it doesn't occur.

Here's a short recording from the demo page directly.

Does anyone have any idea how to fix this?

Edit: What do you think about this possible solution?

$(".box1 input, .box2 input").on("input", function() { $(this).blur().focus(); });
