ImageLabel 和 MessageBoxBase 组合使用的时候会产生内存泄漏

ImageLabel 和 MessageBoxBase 组合使用的时候会产生内存泄漏，注意当使用 QDialog 时没有该问题产生

最小复现代码

import requests
from PyQt5.QtCore import QThreadPool, pyqtSignal
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QApplication, QDialog, QPushButton, QVBoxLayout, QWidget
from qfluentwidgets import ImageLabel, MessageBoxBase


class ImageDialog(MessageBoxBase):
    imageDataFetched = pyqtSignal(bytes)

    def __init__(self, parent: QWidget | None = None) -> None:
        super().__init__(parent)
        # self.mainLayout = QVBoxLayout(self)
        self.posterLabel = ImageLabel(self)
        self.viewLayout.addWidget(self.posterLabel)
        self.imageDataFetched.connect(self.setImage)
        QThreadPool.globalInstance().start(self.fetchImage)

    def fetchImage(self) -> None:
        resp = requests.get("https://qfluentwidgets.com/img/features/dark-store.jpg")
        self.imageDataFetched.emit(resp.content)

    def setImage(self, imgData: bytes) -> None:
        img = QPixmap()
        img.loadFromData(imgData)
        self.posterLabel.setPixmap(img)


class View(QWidget):
    def __init__(self) -> None:
        super().__init__()
        self.resize(400, 300)
        self.mainLayout = QVBoxLayout(self)
        self.btn = QPushButton("show dialog", self)
        self.btn.clicked.connect(self.showDialog)
        self.mainLayout.addWidget(self.btn)

    def showDialog(self) -> None:
        dialog = ImageDialog(self)
        dialog.exec()


if __name__ == "__main__":
    app = QApplication([])
    view = View()
    view.show()
    app.exec()
