    applicationwindow: Don't pass for_size < -1 to measure()
    
    If the application window is measured with for_size -1 horizontally,
    this code clearly passes something lower to the parent class measure()
    implementation. Only subtract the menubar_height if we're passed a
    for_size > -1.
