QVTKOpenGLNativeWidget Mac trackpad events appear incorrect in VTK (9.1, 9.2, 9.3-rc2) with Qt6

QVTKOpenGLNativeWidget appears to send a left-mouse-down event when the cursor is moved over the widget in Qt6. This is using a standard apple laptop trackpad and this issue does not occur with an external mouse. So moving the cursor (without clicking) over the widget causes the model to rotate with the default interactor.

This is reproducible with the Minimal VTK-Qt app for VTK 9.1, 9.2, 9.3-rc2, master (18e80402) in Qt6 (tested with Ventura 13.5, Qt 6.5.1 from homebrew). Qt 5.15.10 with VTK 9.1, 9.2, 9.3-rc2 and master (18e80402) does not appear to have a problem
