Prior to this patch we cancel animations in AnimationCollection::Destroy but this is not called automatically when the property holding the collection is destroyed via its destructor. When an element is unbound from the tree we destroy its animation properties but don't call AnimationCollection::Destroy. This means, that in such circumstances: * We won't create animation mutation records for the removed animations * Once we start registering animations with a timeline they won't have a chance to remove themselves from the timeline (meaning document.timeline.getAnimations()) will keep returning them * Once we go to implement the animationcancel and transitioncancel events we won't fire them in this case (assuming we implement the queueing/dispatch of those events as part of the cancel code) This patch addresses this by moving the call to cancel each animations to the property destructor for the animation properties. We do this first so we can land this change separately to ease bisecting any regressions it might trigger. --HG-- extra : commitid : KzukSO91RMH extra : rebase_source : 54ed2aeb69d8bceca424c70c7f33d4bf92d54546
