Source/WebCore:
In order to allow a CSS Transition to be seeked prior to its start time, it needs to have its fill mode set
to backwards. Adding code to set the fill mode in CSSTransition::initialize() yields early timing model
invalidation and we could get in a situation where stylesWouldYieldNewCSSTransitionsBlendingKeyframes()
was called before we had a chance to create blending keyframes for a CSS transitions, since the call
to create blending keyframes is made after the call to initialize(), so we now cater for this case.

Make one test opt into CSS Animations and CSS Transitions as Web Animations and fix expectations for a CSSTransition
test which mistakenly assumes the fill to be "none".
