    While not actually observed as a problem, make sure that we destroy
    the GocItem used for anting.

+       * src/sheet-control-gui.c (scg_unant): Destroy item cursors.  We
+       want them visually gone and g_object_unref does not guarantee
+       that.
+
        * src/sheet.c (sheet_insert_rows, sheet_insert_cols): Clear style
        dependents.  A later step clears and re-applies style completely
        for the moved area.  Fixes #741197.
