Use the official example from the section "CheckBox in group header":


1. Enter edit mode, check the header of a section, so all items in the group are checked

2. Click several times on a single item, so it will check/uncheck
- listView.SelectedItems will start containing duplicate items from the selected group
- the checkbox selection and list selection lose synchronization (and enter a 3-state cycle)
