Attachment: Bug 1823862 - Ship animation-composition.

Other browsers (i.e. Blink and WebKit) have shipped it, and there is no
issue about this, so it's safe to ship this feature.

Release Note Request (optional, but appreciated)
[Why is this notable]: This enables a new feature in Firefox, so developers should be aware of.
[Affects Firefox for Android]: Same as desktop. Just a new feature we start to support.
[Suggested wording]: Support animation-composition property, which provides the declarative way to define the composite operation used when multiple animations affect the same property simultaneously.
[Links (documentation, blog post, etc)]: N/A
