In QMenu, the mouse hover cannot be set

[LuoMeng]

Here is a test case:

from PyQt6.QtWidgets import QApplication, QSystemTrayIcon, QMenu
from PyQt6.QtGui import QIcon, QAction


class TrayIconApp:
    def __init__(self):
        self.app = QApplication([])

        self.tray_icon = QSystemTrayIcon()
        self.tray_icon.setIcon(QIcon("../Pets/MengJi_pro.png")) 

        self.tray_menu = QMenu()

        self.tray_menu.setStyleSheet("""
            QMenu::item {
                padding: 5px 20px;
                text-align: center;
                background-color: white;
                color: black;
            }
            QMenu::item:hover {
                background-color: #0078d7;
                color: white;
            }
            QMenu::item:pressed {
                background-color: #005bb5;
                color: white;
            }
        """)

        self.show_action = QAction("Show", self.tray_menu)
        self.exit_action = QAction("Exit", self.tray_menu)
        self.tray_menu.addAction(self.show_action)
        self.tray_menu.addAction(self.exit_action)

        self.tray_icon.setContextMenu(self.tray_menu)

        self.tray_icon.show()

        self.app.exec()


if __name__ == "__main__":
    app = TrayIconApp()

After I run the code, right click the icon and hover the mouse on the widget, nothing changes in color. I think this is a bug.
