Middle-click paste (X11 primary selection) broken since v1.0.11

[mgajjar-code]

Description

Middle-click paste (X11 primary selection) stopped working in the Copilot CLI chat prompt starting in v1.0.11. It works correctly in v1.0.3.

Environment

• OS: SUSE Linux (kernel 5.14.21)
• Terminal: SSH session with X11 forwarding, TERM=xterm-color
• Display: X.Org X11
• Works in: v1.0.3
• Broken in: v1.0.11

Steps to Reproduce

1. Connect via SSH with X11 forwarding
2. Launch Copilot CLI v1.0.11
3. Copy some text (select with mouse to populate X11 primary selection)
4. Middle-click in the chat prompt to paste
5. Result: Paste does not occur — the mouse event is captured by the app
6. Expected: Text should be pasted, as it does in v1.0.3

Notes

• Shift+Middle-click works as a workaround (bypasses app mouse capture)
• Both versions tested in identical SSH sessions to the same machine, same terminal emulator, same TERM value, same X display
• The regression appears to be caused by a change in how mouse reporting/capture is handled between v1.0.3 and v1.0.11
• Sending escape sequences to disable mouse reporting (\e[?1000l etc.) from within the CLI does not help, as the app re-enables mouse capture on each prompt

Workaround

Use Shift+Middle-click, or downgrade to v1.0.3.

same terminal emulator

What terminal emulator is that?

Sending escape sequences to disable mouse reporting (\e[?1000l etc.) from within the CLI does not help

You can disable this with "mouse": false in your ~/.copilot/config.json.

What changed is that the "mouse": true became the default, alongside the alt screen renderer.
