Unity atlas I: out of sync animations

Hi!

We encountered several problems when exporting an atlas of animations to unity. So here I will write about the first.

Steps to reproduce bug:
1. Create clip with timeline (girl, main-timeline).
2. Create subclip with blinking girl head (with their own timeline).
3. Create girl body animation through different shapes in main-timeline.
4. Export atlas to Unity.

Results:
When play this animation in Unity we can see that girl head moves out of sync with her body. We have investigated, that this happens due to the two different Unity-animation approach are used together. One - is sprite animation (for shapes). And one - is coords animation which work through Unity Animate-component. Theese two are out of sync by time as you can see in video.

Expected results:
Girl's head and body move synchronously.

I think it is a bug and there needs refinement of Unity-plugin.
