        * gtk/gtktreeview.c (validate_visible_area): implement a working
        use_align = FALSE implementation (also mentioned in #91335, reported
        by Juri Pakaste).

        * gtk/gtktreeview.c (validate_visible_area): only free the
        scroll_to_path if we are done with validating (fixes #93584, reported
        and testcase provided by Erik Simonsen).

        * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_cell_process_action):
        set the GTK_CELL_RENDERER_FOCUSED flag where appropriate. (fixes
        #75745, reported by Richard Hult).

        * gtk/gtktreeviewcolumn.c (gtk_tree_view_column_cell_get_position):
        initialize cellinfo to NULL to silence the compiler.
