QApplication.setOverrideCursor() stopped working

`QApplication.setOverrideCursor()` no longer changes the current cursor.
`QWidget.setCursor()` still works though, so changing the cursor itself is not technically broken.

Here is a minimal example that works under PySide6 6.2.4 but doesnt with 6.3.*:

from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QWidget

app = QApplication([])
w = QWidget()
w.show()
# w.setCursor(Qt.WaitCursor)
QApplication.setOverrideCursor(Qt.CursorShape.WaitCursor)
app.exec()
