Question: Why does whole tree re-renders on node modify?

Hi,

First of all, thanks for the awesome component. I've looked at various React trees and this one is the best for my needs.

My tree nodes have modifiable title very similar to the one in the storybook. Using React Dev Tools, I see that the whole tree seems to be re-rendered on each keystroke editing the title (i.e. each onChange of the text Input element). Is expected behavior? What is the reason for this? Due to this, I feel compelled to use an uncontrolled form input and update the tree only on onSubmit and onBlur events. Would making nodes PureComponent prevent the re-render? If so, would this mean using nodeContentRenderer to override NodeRendererDefault?

Thanks.
