    page: use scroll_to_mark() for goto line
    
    This should bring the destination mark within .25 of the middle of the
    widget. However, it doesn't actually seem to be doing that as it's always
    bringing it to exactly the .5 position.
    
    This used to work in GTK 3, so there is definitely something to investigate
    upstream in GTK 4.
