Slides don't change in nested components

Changing of slides (via data inputs) in nested components (components inside another component) doesn't work but without nesting (if just put the same component to scene) the slides changes.

I've attached a test application which will help you to reproduce the issue.

The application draws two text elements: left - in component, right - in nested component.

Expected result: by typing keys (pointed in README of app) both elements go to looping slides with static animation on the element' opacity.

Actual result: only left element goes to another slide.
