Parent ListView element also becomes selected when inner ListView element is selected

How to reproduce:

1. Open attached “IN-139732_ListView_in_ListView_selection” project
2. Select inner element in “TestScript” window
3. Observe the highlighting

Actual result: Both parent ListView element and child ListView element are selected
Expected result: Only child ListView element is selected

Reproducible with: 2023.1.0a10, 6000.0.73f1, 6000.3.13f1, 6000.4.3f1, 6000.5.0b4, 6000.6.0a3

Reproducible on: Windows 10 (User), Windows 11
Not reproducible on: No other environments tested

Notes:

• Hovering over an element overrides highlighting when parent ListView is selected and highlighted
• Selected inner element becomes indistinguishable from other inner elements in a selected ListView
• Similarly to selecting, other actions are called multiple times. If one would make both ListViews reorderable, selecting an inner ListView’s element will throw an error: “Starting multiple Drags. You can only start one drag at a time!”
