I would suggest also hiding this lazy initialization by an inline function like:

bool isAnimationAvailable() { return m_animations; }

> Source/WebCore/platform/graphics/ca/GraphicsLayerCA.cpp:2864
> +void GraphicsLayerCA::ensureLayerAnimations()
> +{
> +    if (!m_animations)
> +        m_animations = std::make_unique<LayerAnimations>();
> +}

I would suggest writing this function like this:

LayerAnimations& GraphicsLayerCA::ensureLayerAnimations()
{
    if (!m_animations)
        m_animations = std::make_unique<LayerAnimations>();
    return *m_animations;
}

And replace all the instances of m_animations with ensureLayerAnimations(). This will make it clear that m_animations should not be accessed directly since it can be nullptr. But calling ensureLayerAnimations() is always safe to use.
