[ScrollAnimation] Better handling of Component destruction to complete the animation

ScrollAnimation is based on withMountWhenInView so when user is scrolling fast the element can be destroyed in the middle of the animation.

Ex: animated play range between 0 and 1. Fast scrolling leave the animation state at 0.8 cause component get destroyed
