Changing isExpanded props in TreeNode to false doesn't change TreeNode inner state

Detailed description

As TreeView and TreeNode aren't officially released yet I've copied the source code directly to our app.

The problem is with the isExpanded prop. In my scenario, I need the button to collapse all nodes at once. To do so I am using isExpanded prop of the TreeNode component.
Information about the expanded or collapsed node is stored in redux. So when collapse all button is clicked I'm setting isExpanded prop to false. Unfortunately, it doesn't collapse the nodes. Prop changes to the false but the inner state doesn't (see the gif below).
