Attempting to select a comboBox value with a down arrow key press when there is only a single item in array results in a crash.

I'm adding a link to a modified version of combobox demo showcasing the error.
Steps for reproduction:

1. Select comboBox field
2. Click arrow key down to select first and only entry in the comboBox

The React ComboBox and Autocomplete do not support the valueRender prop, so a selected value cannot have a custom display. The DropDownList does however - they should all be consistent in this.
