    Description

      With the attached pyside2095.py (mouse click)

      Python 3.11.0
      Qt 6.4.1 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 11.3.0)
      handler1 1 type= AlignmentFlag
      Traceback (most recent call last):
        File "/home/frkleint/pyside2095.py", line 27, in mousePressEvent
          self.test_sig2.emit(Qt.AlignLeft, "bla")
      TypeError: test_sig2(PyObject) only accepts 1 argument(s), 2 given!
      

      as opposed to

      Python 3.10.6
      Qt 6.4.1 (x86_64-little_endian-lp64 shared (dynamic) debug build; by GCC 11.3.0) [limited API]
      handler1 AlignmentFlag.AlignLeft type= AlignmentFlag
      handler2 AlignmentFlag.AlignLeft type= AlignmentFlag bla
      

      The signal with 1 parameter works, note though that the enum is printed as int in 3.11. The signal with 2 parameters does not work.

      First noticed on the tabbedbrowser example:

      p examples\webenginewidgets\tabbedbrowser\main.py
      
      Traceback (most recent call last):
        File "C:\dev\pyside\pyside-setup64i\examples\webenginewidgets\tabbedbrowser\browsertabwidget.py", line 100, in _current_changed

        File "C:\dev\pyside\pyside-setup64i\examples\webenginewidgets\tabbedbrowser\browsertabwidget.py", line 108, in _update_actions
          self._check_emit_enabled_changed(web_action, enabled)
        File "C:\dev\pyside\pyside-setup64i\examples\webenginewidgets\tabbedbrowser\browsertabwidget.py", line 97, in _check_emit_enabled_changed
          self.enabled_changed.emit(web_action, enabled)
      TypeError: enabled_changed(PyObject) only accepts 1 argument(s), 2 given!
      Traceback (most recent call last):
