Description

  • ListBox.SelectedIndexCollection and ListBox.IntegerCollection have IsSynchronized == true
  • ListBox.SelectedObjectCollection and ListBox.ObjectCollection have IsSynchronized == false

It appears both are actually not synchronized, so should return IsSynchronized == false

Contributor guide

Research direction
Locate the ListBox.SelectedIndexCollection, ListBox.IntegerCollection, ListBox.SelectedObjectCollection, and ListBox.ObjectCollection classes and modify their IsSynchronized property to return false.
