Can either of those be references instead of pointers?

> Source/WebCore/page/animation/AnimationBase.cpp:76
> +    , m_animation(const_cast<Animation&>(animation))

If we are keeping a reference, maybe we should be taking a reference, not a const reference.

> Source/WebCore/page/animation/AnimationBase.h:53
> +    WTF_MAKE_FAST_ALLOCATED;

What changed here? Are we now allocating these on the heap for the first time? Or were we using the wrong alloc?

> Source/WebCore/page/animation/AnimationBase.h:150
> +    void setAnimation(const Animation& animation) { m_animation = const_cast<Animation&>(animation); }

I don’t understand why this takes a const Animation& and not an Animation&.

> Source/WebCore/page/animation/CompositeAnimation.cpp:66

This should be:

    for (auto& transition : m_transitions.values()) {

> Source/WebCore/page/animation/CompositeAnimation.cpp:67
> +            animationController().animationWillBeRemoved(transition);

This will need to do transition.get(), but otherwise should be fine. Of course, animationWillBeRemoved should take a reference, and then it would be *transition.

for (auto* animation : m_keyframeAnimations.values() {

for (auto& transition : m_transitions.values())

The string here should be named something other than "it". It’s not an iterator. Its type is AtomicStringImpl*, so I think maybe it’s animationName?

Not sure about the types here, but I think this can use m_animation.ptr() instead of &m_animation.get().

for (auto& widget : overlapTestRequests.keys())

Probably should name this "request" rather than "it".
