Search input clears on selection

[TrevorBurnham]

Steps to replicate:

1. Go to the example page
2. Type "south" in the "States" example
3. Press Enter to select "New South Wales"
4. Tab out and back in

After these steps, the search input is clear. By contrast, on the react-select example page, the search query "south" is shown again in the input when you tab back into it. I'm not sure yet what's causing the discrepancy.
