    Fixup 89394bcd: handle cursor keys from keypad
    
    Due to a macOS peculiarity, it is necessary to handle KeypadModifier.
    We do it unconditionnally, although only macOS seems to be affected.
    
    "Note: On macOS, [...] The KeypadModifier value will also be set when
    an arrow key is pressed as the arrow keys are considered part of the
    keypad." (​https://doc.qt.io/qt-6/qt.html#KeyboardModifier-enum)
    
    Related to bug #12572.
