[Bug] Scroll input bound to message history prevents viewing previous results
Bug Description I'm unable to scroll back up to look at old results, because somehow you have bound the scroll up and scroll down to your input field. that's super-unhelpful, please revert that change.

This seems contained to a specific session, but persists across separate claude code runs, provided the session is resumed. It does not immediately recur with similar tasks in the same project folder.
The binding of the scroll wheel to up-down on commands persists in the terminal which claude ran in, but goes away with a reset, suggesting it is in some way connected to terminal settings. The reset doesn't prevent a resumption from retriggering the issue.
Same issue here. Let me ask you, have you added a lot of configuration (hooks, commands, etc.) to Claude Code? I just finished a reusable Claude Code configuration to help rebuild context after compaction, and do some other things. Shortly after I deployed it to this project, I began to see the issue, and not once before I deployed it.
No, I'm using pretty stock Claude with only one MCP (Grafana). I think it was the result of interpreting terminal characters in the output of a command, and then preserving them somehow in the displayed context.
