gtk3: GtkTreeView::gtk_widget_get_preferred_size can return a poor height

if GtkTreeView's internal do_validate_rows hasn't been run yet,
guarantee that's called by calling gtk_widget_get_preferred_width.

this is noticable in the calc autofilter color dropdown on getting
its preferred height right after inserting rows into it
