What happened?

DetailedMessagesDisplay renders the entire history in a ScrollableList. While virtualized, the underlying data structure and React nodes for thousands of past turns can consume significant memory.

What did you expect to happen?

Limit the number of turns kept in active React state or implement more aggressive off-screen node pruning.
