This could be the case when JavaScript is disabled. Note that, in `Poll/WebVote` we're calling `given_answers` inside a transaction. Putting this code before the transaction resulted in a test failing sometimes, probably because of a bug that might be possible to reproduce by doing simultaneous requests.
