Enable/Disable Sprite renderer as a part of Animation (*.anim track)

I wanted to ask if enabling/disabling renderers from animation track has some limitations I dont know about. The problem is following: I was working on a special effect system (for things like muzzle flashes). The idea was to put everything that is happening to the "effect" object (including visibility switching) to the animation track. Then I would manipulate the Cycle Offset of this animation from script to both show/hide the object and animate it. But for some reason, turning Sprite renderer on/off does not work with such setup. Other keyframes (such as Scale) play as intended, but if I try to keyframe the renderer, it stays at its first frame state (Disabled in my case)

 

Did you ever find a solution? I am having a VERY similar problem with my project
