### Ionic Framework Version

v8.x

### Current Behavior

When using the scrollwheel to scroll through the options in an `` element, and it gets to the end of the options list, I cannot scroll to other options anymore without first moving the mouse cursor.


This makes selecting an item in `` feel sluggish.

### Expected Behavior

When reaching the end of the list of items in an `` element, the scrollwheel should be able to still move through the list of items, without needing a cursor movement.

### Steps to Reproduce

### Code Reproduction URL

### Ionic Info

### Additional Information

_No response_

Start with the ion-picker component using the reproduction URL in the issue, and reproduce the scrollwheel behavior at the end of the options list. The work is done when the wheel can continue moving through the options without requiring cursor movement.
