Setting Qt::PartiallyChecked to QTreeWidgetItem is broken in 5.11.0 and 5.11.1.
Steps to reproduce the issue:
- Execute the attached program with QT 5.10.1, all checkboxes are in the desired state.
- Execute the same program with Qt 5.11.0 and 5.11.1, the third checkbox which should be in partial state, is in checked state.
Expected result: Partial checked checkbox should have correct state.
Working fine with Windows. Attaching the output snapshots also.
