bug: Ctrl+Z does not undo pasted prompts in Amazon Q VS Code

[Mathi-MS]

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

If you're using the same Windows setup as before:

Expected behaviour

When I type a prompt manually in Amazon Q and press Ctrl+Z, the text is undone correctly.

I expect the same behavior when I copy and paste a prompt. Pressing Ctrl+Z should undo the pasted text.

Actual behaviour

When I copy and paste a prompt into Amazon Q in VS Code and press Ctrl+Z, the pasted text is not undone.

Interestingly, Ctrl+Z works correctly when the prompt is typed manually.

This is a small issue, but it can be frustrating when working in a rush. It happens repeatedly and interrupts the workflow because I have to manually remove or correct the pasted prompt.

I have attached a video demonstrating the issue.

Steps to reproduce

1. Open VS Code with Amazon Q Developer.
2. Open the Amazon Q chat/input area.
3. Type some text manually.
4. Press Ctrl+Z — the typed text is undone correctly.
5. Copy a prompt/text from another application.
6. Paste the prompt into Amazon Q.
7. Press Ctrl+Z.
8. Observe that the pasted prompt is not undone.

Expected: The pasted prompt should be removed/undone.

Actual: Ctrl+Z does not undo the pasted prompt.

Environment
