Tag input disabled when entering a tag that exists in two namespaces

[parelius]

Thanks for this great package. It works fine for me but I see an issue when a tag is used in more than one namespace.
As soon as I start entering a such a tag and the characters entered make the tag unambiguous, the tag input field does not accept any inputs: Clicking on a suggestion does not enter it and I can't enter a new tag by hitting the enter key.
