    Get which-key--buffer's window from any frame
    
    Previously we assumed the buffer was being displayed in a window
    of the current frame, which isn't the case if e.g. a child frame
    is being used.
    
    We also cannot assume that the third-party code that sets up such
    a child frame also deletes it.  `which-key-posframe' for example
    merely hides it.
