^ Anything else needed here?


RenderBlock* RenderObject::containingBlock() const
{
    if (is<RenderText>(*this))
        return containingBlockForPositionType(PositionType::Static, *this);

    auto containingBlockForRenderer = [](const auto& renderer) -> RenderBlock* {
        if (isInTopLayerOrBackdrop(renderer.style(), renderer.element()))
            return &renderer.view();
        return containingBlockForPositionType(renderer.style().position(), renderer);
    };

    if (!parent() && is<RenderScrollbarPart>(*this)) {
        if (auto* scrollbarPart = downcast<RenderScrollbarPart>(*this).rendererOwningScrollbar())
            return containingBlockForRenderer(*scrollbarPart);
        return nullptr;
    }
    return containingBlockForRenderer(downcast<RenderElement>(*this));
}
