I think we should just include this unconditionally.

> +#ifndef NDEBUG
> +void showScrollingStateTree(const WebCore::ScrollingStateTree* tree)

Please add a blank line here.

Silent? Maybe print something for clarity?

> Source/WebCore/page/scrolling/ScrollingStateTree.cpp:259
> +    const WebCore::ScrollingStateNode* rootNode = tree->rootStateNode();

I would just do auto* here; the complete typename and const is utterly uninteresting.

Silent? Maybe print something for clarity?

> +#ifndef NDEBUG
> +void showScrollingStateTree(const WebCore::ScrollingStateTree*);
> +void showScrollingStateTree(const WebCore::ScrollingStateNode*);
> +#endif

Does it really need to be in the header? Can’t we just put this at the top of the .cpp file?
