Hi Aleksei,

The default value for 'composite' attribute is specified as null (

However if keyframe input contains attribute 'composite' with the value
null, the procedure for converting an ECMAScript value to an IDL
enumeration type <http://www.w3.org/TR/WebIDL/#es-enumeration>[WEBIDL]
<http://w3c.github.io/web-animations/#biblio-webidl>
will throw TypeError, because null does not belong to CompositeOperation
<http://w3c.github.io/web-animations/#compositeoperation> enum.
If I've understood the issue correctly, then I think we should handle
null correctly in the procedure for processing keyframe objects. This
applies to both 'composite' and 'offset'.
I've made a change to that effect:
https://github.com/w3c/web-animations/commit/957350a0c2bb140a30030d70bf7a9ddc3dda5cca
Please let me know if I've misunderstood the issue.
Best regards,
Brian
