PySide6 multithreading work incorrectly with debugger

I reported this problem in a thread of Qt Forum before. Other people also encountered this problem earlier than me (stackoverflow). 

The minimal example is attached below. Worker.run should be executed in child thread. When using Run in PyCharm, it's correct. However, when using Debug with the same configuration, it's in main thread. This piece of code is corrected by @friedemannkleint from Qt and examined several times by myself, so it should have no bug (see Qt Bug Tracker).

import sys

from PySide6.QtCore import QObject, Signal, QThread, Qt, Slot, QLibraryInfo, qVersion
from PySide6.QtWidgets import QMainWindow, QApplication


class Worker(QObject):
    update = Signal()

    def run(self):
        print(f"worker.run(): {QThread.currentThread().objectName()}")
        self.update.emit()


class Window(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setObjectName("Window")
        self._worker = Worker()
        self._worker.setObjectName("worker")
        self._thread = QThread(self)
        self._thread.setObjectName('test thread')
        self._worker.moveToThread(self._thread)
        self._thread.started.connect(self._worker.run)
        self._worker.update.connect(self.slotUpdate)
        self._thread.start()

    def closeEvent(self, e):
        self._thread.quit()
        self._thread.wait()
        e.accept()

    @Slot()
    def slotUpdate(self):
        print(f"window.update(): \"{QThread.currentThread().objectName()}\"")
        print("  window.thread()=", self.thread())
        print("  worker.thread()=", self._worker.thread())
        print("  worker.thread()=", self._thread.thread())


if __name__ == '__main__':
    print('Python {}.{}.{}'.format(sys.version_info[0], sys.version_info[1],
                                     sys.version_info[2]))
    print(QLibraryInfo.build())
    app = QApplication()
    w = Window()
    w.setWindowTitle(qVersion())
    w.show()
    sys.exit(app.exec())
