Current behavior
In the example from the documentation OrderList component, there is a "dataKey" field in the props. But the OrderList component doesn't use these props. As I see OrderList saves object reference to use it to current selections. This approach gives rise to problems if change OrderList "value".
I wrote a little example on codesandbox.io. try to change order after delete element or add or update.

Expected behavior
I think using "dataKey" instead of object reference will solve this problem. Also, I founding a good idea to add "selectedDataKey" and "onChangeSelected" callback to props. It will help easier make solutions as I show in codesandbox.io.
