[React][Combobox] Keep the selected option active

[JesusTheHun]

Following #1178 but with a different use case.

Check this : https://stackblitz.com/edit/react-dw9luu?file=src/App.js

Open the console.
Using the keyboard, select a person in the list. Now press Cmd/Ctrl + ArrowLeft.
The person is programmatically set to Kenton Towne.
The input still has the focus, but the selected value is not active, which means if I press Enter it won't trigger a value change.

My use case is a multi-step combobox when you are prompted for more choices one after another. When you go back (because you think missclicked for example) you should be able to just press enter again to validate your value.

I think one of the solution to this problem would be to have an optional alwaysActive prop on Options

<Options alwaysActive>
  <Option value="id1">First Option</Option>
  <Option value="id2">Second Option</Option>
</Options>

This would not break the logic since currently, if you select a value, and then press ArrowDown it will activate the selected option.
