Copilot CLI confirmation card can't be dismissed

### Describe the bug

Copilot cli still says "Copilot needs information" after answering the question? It leaves the session mostly useless because you can't give it more instructions unless there are more questions and it will get back to the same bad state after you answer it. The only way out is to terminate the powershell session by clicking the 'x'(ctrl-c doesn't work either) This has been happening for a week for most of my copilot cli sessions and I have been updating to the new version but it still happens.


I'm using copilot cli through powershell on win11.

### Affected version

1.0.71 and possibly a few previous versions

### Steps to reproduce the behavior

1. Prompt a design question like "design a calculator app with me and brainstorm with me with only 1 question"
2. Select any option (I selected the first recommended one)
3. See the "Copilot needs information" card not being dismissed while the agent is generating result


### Expected behavior

The question card would be dismissed and user can keep interacting with the agent through the same cli session_

### Additional context

_No response_

Windows 11 の PowerShell で Copilot CLI 1.0.71 を使用し、design-question の手順に従ってこれを再現し、オプションを 1 つ選択します。CLI のエントリーポイントから confirmation-card と session のやり取りを追跡します。完了とは、回答後にカードが閉じられ、ユーザーが同じ session で引き続き指示を送信できることを意味します。
