[Python] persistent issue with PyQt6 QtWebEngine

In Chrome, if you close the pop up dialog of this page, then it won't show if you open the page again. However, in my following code, the pop up dialog still shows in a second run even you close it in the first run, it seems to be a issue with the persistent storage, but I don't know how to solve the issue, any help?

class WebEngineView(QWebEngineView): # QWebEngineView
def __init__(self, parent=None):
super().__init__(parent)

self.webpage = QWebEnginePage()
# self.webpage.javaScriptConsoleMessage = lambda level, message, lineNumber, sourceID: print(message) # if level > QWebEnginePage.WarningMessageLevel else None # 关闭js console msg，不起作用→self.javaScriptConsoleMessage = None;https://doc.qt.io/qt-5/qwebenginepage.html#JavaScriptConsoleMessageLevel-enum

self.setPage(self.webpage)
self.webpage.load(QUrl('https://fanyi.baidu.com/'))

if __name__ == "__main__":
app = QApplication(sys.argv)
webEngineView = WebEngineView()
webEngineView.showMaximized()
sys.exit(app.exec())
