    libview: Open annotation windows when opening the document
    
    By right clicking an annotation and selecting "Annotation Properties...",
    there exists an option called "Initial window state" which regulates
    whether the annotation window should be opened when opening the document.
    This behavior was altered by commit aed1af6fa7ad6ccc17c826a8e9df6dfb7bea29fe,
    whose purpose was exactly to prevent annotation windows from opening
    for performance reasons.
