shibokensupport/signature/parser.py . . . UNRECOGNIZED: 'QFileDialog.*'

Hi:

Talk about 6 degrees of separation; ok, maybe not that many. 

I am here because I started to experiment with the pure-python web-development framework Rio; and, during the very first tutorial, I got some messages at the terminal.  I reported this at Rio, but they tell me there is nothing they can do, that Rio depends on pywebview and that pywebview depends on pyside6; so, here I am. 

So, I am here to report that while running the Rio app, I get a bunch of messages like these:

shibokensupport/signature/parser.py:266: RuntimeWarning: pyside_type_init:_resolve_value        UNRECOGNIZED:   'QFileDialog.ViewMode'
        OFFENDING LINE: '1:PySide6.QtWidgets.QFileDialog(self,parent:PySide6.QtWidgets.QWidget,f:PySide6.QtCore.Qt.WindowType,*:KeywordOnly=None,viewMode:QFileDialog.ViewMode=None,fileMode:QFileDialog.FileMode=None,acceptMode:QFileDialog.AcceptMode=None,defaultSuffix:QString=None,options:PySide6.QtGui.QAbstractFileIconProvider.Option=None,supportedSchemes:QStringList=None)'shibokensupport/signature/parser.py:266: RuntimeWarning: pyside_type_init:_resolve_value        UNRECOGNIZED:   'QFileDialog.FileMode'

If his is a bug, now you know; if there is anything I can do on my end to fix, please advise. 

Thanks.
