Pyright: 'Object of type "overload" is not callable' for Q... constructors

Pyright flags the right hand side of the third line here as Object of type "overload" is not callable:

import sys
import PySide2.QtWidgets as widgets
app = widgets.QApplication(sys.argv)

The same applies to constructors and other methods of many more classes.

Note added after more research: Pyright seems to get confused by the try: import typing at the beginning of each of PySide's .pyi files.
