Works Great!!
But when you have more that one token inputs on the page, it fails on within(:css, ".token-input-dropdown") because there will be more than one ".token-input-dropdown" elements on the page.
Changing it to within(:css, ".token-input-dropdown:not(:empty)") will fix it.

A slight addition within(:css, ".token-input-dropdown:not(:empty)") will fix it

I had some trouble with Capybara 2.1, so I forked it and tweaked things a bit to fix it: https://gist.github.com/ddonahue99/6116406
