>+        We change the "cssAnimationsAndCSSTransitionsBackedByWebAnimationsEnabled" flag to be called
>+        "webAnimationsCSSIntegrationEnabled" instead. Both the main Web Animations and the new CSS
>+        integration flags are off by default, and turning the main Web Animations flag off makes CSS
>+        Animations and CSS Transitions run on the legacy animation engine.
>+
>+        We also ensure we always call into both CSSAnimationController::cancelAnimations() and
>+        AnimationTimeline::cancelDeclarativeAnimationsForElement() since we want teardown of animations
>+        to be performed no matter which animation code path is used. What that in mind, we don't
>+        conditionalize the CSSAnimationController-related ASSERT() in FrameView::didDestroyRenderTree().
