[v9] Change spring config based on local state

[aleclarson]

Trying to change spring config depending on the state, but there is some strange behavior.

Example 1. Expected behavior: on mount animation plays once and stops. Press "Start looping an animation" — animation begins its infinite loop. Then press "Stop looping an animation" — animation stops. Current behavior: on mount animation plays once and stops. Press "Start looping an animation" — animation begins its infinite loop. Then press "Stop looping an animation" — animation continue looping.

Example 2. Expected behavior: on mount animation plays infinite loop using "DEFAULT_ANIMATION_CONFIG". Press "Start playing" — animation plays infinite loop using PLAYING_ANIMATION_CONFIG. Then press "Stop playing" — animation plays infinite loop using "DEFAULT_ANIMATION_CONFIG". Current behavior: on mount animation plays infinite loop using "DEFAULT_ANIMATION_CONFIG". Press "Start playing" — animation plays infinite loop using PLAYING_ANIMATION_CONFIG. Then press "Stop playing" — animation is broken.
