Duplicate items in listView.SelectedItems when using group header samples

Use the official example from the section "CheckBox in group header":
https://help.syncfusion.com/xamarin/sflistview/grouping#checkbox-in-group-header

http://www.syncfusion.com/downloads/support/directtrac/general/ze/CustomSelectionCheckBox650348378

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
Effect:
- 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)
