Fixed the keyboard navigation for ListView's item foldouts.
How to reproduce:
1. Open the attached “selecting.zip” project
2. Open “SampleScene” Scene (Assets > Scenes)
3. Select “GameObject” GameObject
4. In the Inspector window, expand “My Script” in Component
5. Select any element with a cursor
6. Press the right arrow and observe the result
Expected result: Element is opened
Actual result: Element is not opened
