In regards to Web Intent click events (https://dev.twitter.com/docs/tfw/events), your docs state the following about the “region” property returned in the event:
“region - string: Extended detail indicating where in a widget a user clicked. For example, button, count, or screen name portions of Tweet button or Follow button integrations, or tweet actions within embedded Tweets.”
Extended detail? I get nothing but “region: intent”.
Example: I cannot track Analytics for Retweet intents, because the Reply and Favorite buttons fire the exact same intent events.
