Switching from one card to another in a deck using a <go> task fails. Cache policy is set to ReturnCacheDataDontLoad for the default GET method, which creates problems on Mac. We also do too much work for internal deck jumps (setActiveCardInDocument shouldn't be called from WMLGoElement::executeTask, for internal deck jumps).
