  • Fixed an issue with the unobserve method which, when it was invoked on the last observed element, was preventing already gathered active observations from being delivered. This issue was reproducible only when this method was used in a callback of another observer.

Before this fix content rectangle of a root element contained wrong dimensions. Now it's being handled as a special case of HTMLElement.

Fixed this issue.

It was decided to remove the usage of "getAnimations" and "transition"/"animation" start events due to the small number of browsers that support them.
