When CommonTabListWidgetBase and ScrollBox are arranged vertically, tabs within CommonTabListWidgetBase momentarily become selected when scrolling the ScrollBox upward

When attempting to scroll the ScrollBox upward, the cursor briefly shifts focus to another widget (CommonTabListWidgetBase).
When logging this behavior using LogSlate VeryVerbose, it can be observed that a significantly larger number of logs are generated compared to normal cursor movement.

1. Open the attached reproduction project
2. Connect a controller and launch the project
