Chrome does not track the Onchange event if the cursor goes outside the object, how to fix it?

Question

JavaScript

The essence is this:
the event is tracked on the select element, the onchange or onclick event, it doesn’t even matter, because. here in both cases chrome has the same problem. It is worth highlighting the list below and moving the mouse outside the list, as the event will not work, this is only observed in chrome, even the notorious IE can. How to fix the problem? I thought to put it on onclick at the same time, but it's the same with it.

Are you writing a custom select?
