      Description

      `QGraphicsItem` created via `QGraphicsScene.addRect()` cannot receive mouse press event.

      In following code, `item1` works as expected, but `item2`'s handler will never get called.

      from PySide2.QtWidgets import (QApplication, QGraphicsRectItem, QGraphicsScene, QGraphicsView)
      
      app = QApplication()
      scene = QGraphicsScene(0, 0, 400, 400)
      
      item1 = QGraphicsRectItem(0, 0, 200, 400)
      scene.addItem(item1)
      item1.mousePressEvent = lambda event: print('#1', event)
      
      item2 = scene.addRect(200, 0, 200, 400)
      item2.mousePressEvent = lambda event: print('#2', event)
      
      view = QGraphicsView(scene)
      view.show()
      app.exec_()
