Escaping out of question/prompt mode leaves session stuck — cannot cancel with Esc or Ctrl+C

[ericnewton76]

Describe the bug

When the agent asks a question (e.g. via a multiple-choice prompt or freeform input), pressing Escape to dismiss the question causes the interface to become unresponsive. The session continues processing in the background, but:

• Esc no longer stops generation
• Ctrl+C no longer interrupts
• The only recovery is to kill the terminal or the process entirely

Steps to reproduce

1. Start a Copilot CLI session
2. Give a prompt that causes the agent to ask a clarifying question (multiple-choice or freeform)
3. Press Esc to dismiss/cancel the question instead of answering it
4. Observe: the agent continues processing but the UI no longer responds to Esc or Ctrl+C

Expected behavior

Pressing Esc during a question prompt should cleanly cancel the question and return to the normal input state, with Esc and Ctrl+C remaining functional for interrupting generation.

Environment

• OS: Windows
• Copilot CLI version: v1.0.24

Additional context

This may be related to the input handler not properly restoring keybinding state after the question prompt is dismissed.

Also, it seems like i have to /restart to get it to reset. If I run any commands, Esc and Ctrl+C are ignored while the agent is thinking/operating.
