The main container's id is a UUID with dashes (uc-3f2504e0-4f89-41d3-9a0c-0305e82c3301). Updating it used to throw in AUC.register's eval and abort later scripts in the same response - silently killing the AjaxUpdateTrigger inside it. Now: bumping the main container should update its count AND fire the trigger that refreshes the second container.
Main count (UUID-id container): 0
Bump main (morph the UUID-id container)Triggered container render count (bumped each time the trigger refreshes it): 1
