Large form select options scroll broken

When scrolling through large form select options (like a list of countries or states) and clicking an option, the list immediately scrolls to the top of the options and makes a selection from the that area instead.

It looks like the click, change, or scroll events are being intercepted after user input or the selected index is incorrect in UI. By testing on click and change, I was able to see that a click event returned the correct selected value and the change event returned the incorrect selected value as described above.

To give a better visual with a short list, imaging seeing A, B, and C as form select options. Then you scroll down to see D, E, F. When you click on E, the options scroll back to the top and B is selected.
