/**
* A ReactNodeView that handles React components sensitive
* to selection changes.
*
* If the selection changes, it will attempt to re-render the
* React component. Otherwise it does nothing.
*
* You can subclass `viewShouldUpdate` to include other
* props that your component might want to consider before
* entering the React lifecycle. These are usually props you
* compare in `shouldComponentUpdate`.
*
* An example:
*
* ```
* viewShouldUpdate(nextNode) {
* if (nextNode.attrs !== this.node.attrs) {
* return true;
* }
*
* return super.viewShouldUpdate(nextNode);
* }```
