What's Wrong?

When opening a past session from the agents view inside the IntelliJ Claude Code terminal panel, scrolling through the session history is completely broken — no scrolling works at all.

Actual Behavior

Scrolling is completely non-functional. The session content is displayed but cannot be scrolled — the view is stuck and no input moves it.

What Should Happen?

Scrolling through the session history should work normally, allowing the user to read previous messages in the conversation.
