            Bug ID: 188730
           Summary: [Web Animations] Animation with a single keyframe is
                    not accelerated
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Animations
          Assignee: webkit-unassigned at lists.webkit.org

const animation = document.body.appendChild(document.createElement("div")).animate({
    opacity: 0
}, 5000);

The following animation fails because in KeyframeEffectReadOnly::applyPendingAcceleratedActions() the keyframes we pass to RenderLayerBacking::startAnimation() and eventually to GraphicsLayerCA::animationCanBeAccelerated() (via GraphicsLayerCA::addAnimation()) only have a single value and we need at least two values to have a qualifying accelerated animation.
