Animate Tree subnodes on select

[ickata]

What problem does this feature solve?

Currently, when the user selects a Tree Node that has sub-nodes and we want those sub-nodes to expand, they are expanded without animation. While expanding/collapsing a parent Node has animation.

What does the proposed API look like?

Maybe introduce a new bool prop animateOnSelect or something.

Could you provide a gif or screen record video?
