How to reproduce:
1. Open the attached “IN-135865” project
2. Open the scene “SampleScene”
3. Enter Play mode
4. In Game view, observe the ListView UI element
Actual result: ListView has a horizontal scroll bar
Expected result: ListView has no horizontal scroll bar
Reproducible in: 2023.1.0a1, 6000.0.70f1, 6000.3.10f1, 6000.4.0b11, 6000.5.0a8
Reproducible on: Windows 11
Not reproducible on: No other environments tested
Workaround: Retrigger “listView.horizontalScrollingEnabled” by toggling it to “true” and then back to the intended value “false” with a script
Note: m_HorizontalScrollingEnabled is “false” by default in the BaseVerticalCollectionView, however, the ScrollView's horizontalScrollerVisibility is “Auto” by default. The first line of the property checks if m_HorizontalScrollingEnabled has changed, if it hasn't, nothing is applied.
