Problem when animating canvas controls

Anyone know what could stop (other than a bug) canvas controls such as buttons or images not working with animations. I was testing copies of old projects and added animator with animation to a panel and animated its color and child controls isActive properties. All worked fine but at some point it stopped animating runtime pretty much everything else than rect transform properties. If I scrub the timeline in the editor the color and active properties are animated.

I tried to create new empty repro project and see if I can do the same there but no luck yet.

They are working here for us, and we use this in the demo scenes. If you really thing it’s an issue please log a bug.

I could not get over this problem and happens inconsistently so bug submitted (Case 631228)

Thanks.
