Combobox: disableCreateItem deletes entry

[silvalaura]

On Combobox with disableCreateItem, if you start typing an item that doesn't exist on the list, pressing enter clears the field.

Expected behavior
Pressing enter keeps the content on the input, and the user has to manually delete it (or click away from the input, onBlur)
Note: This behavior occurs in the Typeahead example
