Sorry, something went wrong.
focus_get(), focus_displayof(), focus_lastfor() and winfo_containing() now return None instead of raising KeyError when the focused widget was not created by tkinter (for example a torn-off menu). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

focus_get(), focus_displayof(), focus_lastfor() and winfo_containing() map a Tcl widget name to a tkinter instance via nametowidget(), which raises KeyError for a widget that tkinter did not create (for example a torn-off menu). They now return None in that case instead of failing.
