(I should clarify that responding to changes in the _animated_ value is more difficult than responding to other changes in the computed value.

In order to avoid triggering transitions due to animations, UAs need to distinguish between non-animated style updates and animated style updates. In Gecko we do this using a separate style resolution step for animations and I suspect in order to do transitions properly with regards to inheritance, other UAs will need to do something similar, if they don't already. As a result, while non-animation related changes will get picked up naturally during the animation styling, changes due to animation itself need special handling.

We already have a similar situation with `font-size` and custom properties but those only affect the property values where as this affects the property name mappings.)
