Paused animation
style recalc count: 1
animation-play-state: paused causes very high cpu load because of style invalidation loop https://bugs.webkit.org/show_bug.cgi?id=182436 <rdar://problem/37182562> Reviewed by Dean Jackson. Source/WebCore: Test: animations/animation-playstate-paused-style-resolution.html If the style of an element with 'animation-play-state: paused' is recomputed so it stays paused we would enter zero-duration animation timer loop. * page/animation/AnimationBase.cpp: (WebCore::AnimationBase::updateStateMachine): Don't move to AnimationState::PausedWaitResponse unless we get AnimationStateInput::StyleAvailable (matching the comments). Otherwise just stay in the existing paused state. Remove AnimationStateInput::StartAnimation from assertion as the case can't happen. LayoutTests: * animations/animation-playstate-paused-style-resolution-expected.txt: Added. * animations/animation-playstate-paused-style-resolution.html: Added.
