Visitor profile bug

When I press ‘Load more visits’ button, the only thing that loads is headers of visits and info about it, but not actions. When I press then say ‘64 actions in 39 min 42s’ in loaded visits after previous press - nothing happens. Maybe this is intended? Then how I can view older actions of visitor?

Problem can be reproduced on your demo site:


Thanks, this definitly looks like a bug:
