Time picker onchange event doesn't fire immediately

I have a time picker and I configured an onChange method. If I change the time, don’t touch my mouse, and do nothing else, the method is not invoked. If I move my mouse outside of the browser, it gets invoked pretty much instantly.

This is Chrome 79.0.3945.117 (Official Build) (64-bit)/desktop. Any thoughts?

Please post what code you have used on your page and add any screenshots that you think would be helpful too.

Plus a link to your published site so it can be tested would be great too.
