        This fixes a scrolling bug. Shouldn't cause problems, but you
        never know ... (#81627, testcase by Timo Sirainen).

        * gtk/gtktreeview.c (validate_visible_area): add a temporary
        implemention for non use_align, always update dy and ->top_row
        if we scroll here,
        (gtk_tree_view_clamp_node_visible): reimplement using
        _scroll_to_cell (#73895).
