    Handle massively-delayed selection-changed events for apps like Caja
    
    Normally when a user copies and pastes a file/folder in a file manager,
    we get a selection-changed event from the container of the just-pasted
    item and want to update our location. But when copying and pasting a
    large number of items in Caja, we are placed in a new window for the
    progress and eventually get the aforementioned selection-changed event.
    Therefore, be sure the container is in the active window before updating
    our location.
