Looks good.

> Source/WebCore/page/scrolling/ScrollingTree.cpp:315
> +    auto changeRoot = rootOfScrollingImpactedNodes(changedNode);

auto*

> Source/WebCore/rendering/RenderLayerBacking.cpp:1833
> +    if (roles.contains(ScrollCoordinationRole::Positioning) && m_positioningNodeID) {
> +        LOG(Compositing, "Detaching Positioned node %" PRIu64, m_positioningNodeID);

There is some inconsistency (here and elsewhere) whether these are called "positioning nodes" or "positioned nodes".

> Source/WebCore/rendering/RenderLayerCompositor.cpp:2891
> +            // FIXME: They should be composited alreayd, but may not have nodeIDs yet.

Typo: already

> +// We also have to be positioned, right?
