Previously, calling `BlockContainer::paintable_with_lines()` would cast a `PaintableBox` to a `PaintableWithLines` without verifying that the cast was valid, which isn't the cast for `FieldsetPaintable`, for example. This method now returns null if it isn't poossible to cast to `PaintableWithLines`.
