Disabling either one of “Web Animations” and “Web Animations and CSS Integration”, or both, makes the bug go away.

Changing the target element from a <span> to a <div> makes the animation work as expected. We exit early in KeyframeEffectReadOnly::applyPendingAcceleratedActions() because we fail to get a renderer.
