When I have a multiple dropdown with allowAdditions set to true,
whenever I try to add any items with more than one word (such as 'Criminal Law') and there are no existing matches, the dropdown disappears when I am on 'Criminal' and I press the spacebar. The new addition re-appears again when I start typing 'L'. I think it should not disappear.

I notice that this is the behavior in the semantic-ui's website's demo as well.
(under 'Dropdown' -> 'Tagging and User Additions' -> 'Multiple')
