    Description

      I'm experiencing a weird behavior when using PySide's QComboBox, when the user makes a selection from the drop-down menu.

      Steps to reproduce:

      • After starting the app, open the combo box drop-down menu
      • highlight one item by hovering the cursor above it
      • move the cursor away (the item still being highlighted)
      • click somewhere within the application window.

      Minimal example:

      import sys
      from PySide6.QtWidgets import QApplication, QWidget, QComboBox, QLabel, QMainWindow, QGridLayout
      
      class Widget(QWidget):
          def __init__(self) -> None:
              super().__init__()
              self._layout=QGridLayout()
              self.lbl = QLabel("Choose item:")
              self.cmbbox=QComboBox()
              self.cmbbox.addItem("item1")
              self.cmbbox.addItem("item2")
              self._layout.addWidget(self.lbl,1,1)
              self._layout.addWidget(self.cmbbox,1,2)
              self.setLayout(self._layout)
      
      class MainWindow(QMainWindow):
          def __init__(self):
              super().__init__()
              self._widget=Widget() 
              self.setCentralWidget(self._widget)
      
      if __name__=="__main__":
          app = QApplication(sys.argv)
          mw = MainWindow()
          mw.show()
          app.exec()
      

      After starting the app, open the combo box drop-down menu, highlight one item by hovering the cursor above it, then move the cursor away (the item still being highlighted), then click somewhere within the application window.

      Expected behavior: the drop-down menu closes without user having made a selection.

      Actual behavior: application (GNOME?) crashes.
