--- Comment #5 from Antoine Quint <graouts at apple.com> ---
AnimationControllerPrivate::suspendAnimations() suspends animations in the current frame's document and its associated subframes, but also sets a global ivar to prevent further animations until AnimationControllerPrivate::resumeAnimations() is called:

void AnimationControllerPrivate::suspendAnimations()
{
    if (isSuspended())
        return;

    suspendAnimationsForDocument(m_frame.document());

    // Traverse subframes
    for (Frame* child = m_frame.tree().firstChild(); child; child = child->tree().nextSibling())
        child->animation().suspendAnimations();

    m_isSuspended = true;
}

The m_isSuspended flag was added for https://bugs.webkit.org/show_bug.cgi?id=114915.

I think the internals method should not call directly into AnimationControllerPrivate::suspendAnimations() like it does now, but rather suspend animations for the current document like it used to pre-114915.
