[Bug] Terminal auto-scrolls to bottom during active generation, preventing mid-task history review

Bug Description
Subject: Auto-scroll behavior regression in Claude Code terminal
Hi Anthropic team,
I've been using Claude Code regularly and noticed a behavior change approximately two weeks ago: when Claude Code is actively generating output, the terminal now forcibly auto-scrolls back to the bottom whenever I try to scroll up to read previous responses mid-task.
This did not happen before — I was previously able to freely scroll through the conversation history while Claude Code was still working, without being snapped back to the latest output.
This is a significant usability regression, especially during long-running tasks where reviewing prior context mid-execution is important.
Environment:

Claude Code v2.1.77
macOS
Model: Opus 4.6

Please investigate what changed in recent releases and consider restoring the previous scroll behavior.
Thank you.
