Focus gets lost when new options are passed to React Select

First of all: thank you for maintaining a really useful React component!

We have an application using React, Redux and React-Select. The Redux state is transformed (grouped, sorted and mapped) and used as options for a React-Select component. The redux state is occasionally refreshed.

Since version 3.2.0 of React-Select I observe the following issue: The currently focused element gets reset to the first option whenever the data is refreshed in redux.

I have built a minimal example here: https://codesandbox.io/s/magical-yalow-y2mzb
-> open the dropdown and hover the second or third option.

I found two ways to remove the issue in the minimal working example:

• Downgrade to React Select 3.1.1
• Remove the .map() call (not feasible in the real world example).

My assumption is that the issue was introduced in #4084.
