Is animation of shaders (such as tint) broken in 4.3?

I have vFX that animate the values in a shader/material (such as animating an alpha value for a smoothstep material). Once I’ve updated to 4.3 the animations don’t work anymore.

Is it broken or just a different way to animate the channels now?

Still broken, I don’t even know what Unity is doing anymore.

I found that adding an animation controller and game object sometimes allows the animation to work.
