Fix out-of-screen item can take focus issue

In case of a ListView has a item which takes more than 33% of its height
(result from getMaxScrollAmount), scroll does not move enough to show
all the item. In this case, consecutive arrow scroll moves selection
everytime while scroll may not move that much.

This fixes the issue by checking the visibility of current selection in
advance.
