Dropdown: Blurring the field doesn't trigger `onChange`

Bug Report

Steps

1. Create a Dropdown field with value, allowAdditions, search props.
2. Type something in the SearchInput and press Tab to blur the field.

Expected Result

Blurring the field should trigger an onChange with the value typed in the dropdown.

Actual Result

onChange is not triggered and Dropdown keeps the old value.

Testcase

As far as I checked the problem arises from the fact that setSelectedIndex is not being called before a call to makeSelectedItemActive.

Not sure if that is the right solution but I fixed it with

diff --git i/src/modules/Dropdown/Dropdown.js w/src/modules/Dropdown/Dropdown.js
