QTableView::setEditTriggers(QAbstractItemView::CurrentChanged) inconsistent behavior

When setting a QTableView's edit trigger to QAbstractItemView::CurrentChanged, if the user is editing a cell and clicks in an empty area of the viewport, the editor widget is closed. When the user then clicks back into the same cell again, the editor widget is not created. The user has to first click in some other cell and then click back into the original one. I realize that when clicking in an empty area of the viewport, the editing cell still has focus (as indicated by the dotted outline within the cell). Still, if clicking in the viewport triggers the CurrentChanged signal, closing the editor widget, then clicking back in the cell should also trigger the CurrentChanged signal.
