ui5-input does not scroll when you key arrow down

[codefactor]

Describe the bug
When you press the arrow key to select suggestion in the results, the scroll position does not move. It is necessary to move the scroll because we have an infinite loading results, and we use the scroll position to know that the user wants to see more items.

To reproduce
Steps to reproduce the behavior:

1. Have a search with many suggestions
2. use keyboard to navigate down the suggestions, go beyond the bottom of the scroll

Expected behavior
The scroll should move down so that the next suggestion item becomes visible at the bottom.
