`AcceptDialog`, `Popup` and `PopupMenu` no longer subscribe to "window_input" signal, because that is only sent if it is not an internal signal. Instead they receive events in `_input_from_window`. They ensure that the event is also propagated to their super-function, just like previously the signals would be treated.
