[issue20567] test_idle causes test_ttk_guionly 'can't invoke "event" command: application has been destroyed' messages from Tk

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

These messages are produced because there are non-handled events of destroyed root widget. They are handled when update() is called for other root widget. To get rid of them you should call update_idletasks() before destroying root widget.
