The sliding problem of Copilot CLI

### Describe the bug

When I use Copilot CLI in Idea, I find that the output content slides up and down very unfriendly, and the content in the input box also slides along. In addition, after sliding to the bottom of the latest output content, there will be automatic online sliding, and I can never understand the bottom content.

### Affected version

GitHub Copilot CLI 1.0.18

### Steps to reproduce the behavior

_No response_

### Expected behavior

_No response_

### Additional context

_No response_

首先，在 Idea 中使用 Copilot CLI 時，重現 GitHub Copilot CLI 1.0.18 中描述的捲動行為。觀察捲動時的輸出和輸入框，包括在最新輸出處的自動移動；當兩者都保持可讀且檢視畫面不再意外捲動時，即表示完成。
