# argument. Tested with PySide2 5.15.0, 5.15.2.1 and 5.15.3 and PySide6
|
||
# 6.3.0; older version, down to PySide 1, are probably affected as well [1].

# * PySide2 5.15.0 and 5.15.2.1 silently ignore invalid keyword arguments,

# i.e. passing the `mode` keyword argument has no effect and doesn’t
|
||
# raise an exception. Older versions, down to PySide 1, are probably
|
||
# affected as well [1]. At least PySide2 5.15.3 and PySide6 6.3.0 raise an
|
||
# exception when `mode` or any other invalid keyword argument is passed.
