Multi Select not working as expected for List view widget

Multi select mode does not appear to allow the user to have multiple widgets selected at once as expected.

1. Download the attached project
2. Open the project
3. Right click the widget "MultiSelectTest"
4. Shift click the top widget
5. Shift click the bottom widget
6. Control click multiple widgets

Result: Only one widget is selected as a time (even though the list view's selection mode has been set to multi)
Expected: The user would be able have multiple widgets selected at once in the list view
