I suggest doing this:

auto* map  = [&] () -> HashMap<Element*, ListHashSet<RefPtr<WebAnimation>>>* {
    if (is<CSSTransition>(animation) && downcast<CSSTransition>(animation).owningElement())
        return map = &m_elementToCSSTransitionsMap;
    else if (is<CSSAnimation>(animation) && downcast<CSSAnimation>(animation).owningElement())
        return &m_elementToCSSAnimationsMap;
    return &m_elementToAnimationsMap;
}();

Then in fact you could probably do it with just an auto& and return the objects directly.

Also, you might want to typedef (using) that HashMap type so it's easier to read.

This comment doesn't add anything.

> +        return HashMap<CSSPropertyID, RefPtr<CSSTransition>> { };

You should using/typedef this one as well.

> Source/WebCore/animation/AnimationTimeline.h:82
> +    HashMap<Element*, HashMap<CSSPropertyID, RefPtr<CSSTransition>>> m_elementToCompletedCSSTransitionByCSSPropertyID;

Use using here.
