pasting issue

Describe the bug

Bug: Pasted multi-line content not sent to model

Environment: WezTerm (Ctrl+V →  PasteFrom "Clipboard" ) on Windows, running Copilot CLI inside WSL (zsh). CLI version 1.0.80.

Expected: The full pasted content (12 lines) is sent to the model as part of the message.

Actual: The model responds as if no content was received — e.g., "I don't see the pasted content — it looks like it didn't come through." The paste token is not being expanded/substituted with the real content before the request is sent.

Notes: Terminal/paste mechanism itself works correctly (bracketed paste, WezTerm config verified clean) — this appears to be a CLI-side bug in how paste tokens are resolved before submission.

Affected version

GitHub Copilot CLI 1.0.80.

Steps to reproduce the behavior

Steps to reproduce:
in wezterm using wsl,

1. Copy multi-line text (e.g., 12 lines) to clipboard.
2. Prompt correctly shows a collapsed token:  [Paste #1 - 12 lines] .
3. Press Enter to submit.

Expected behavior

No response

Additional context

Tái hiện trong WezTerm trên Windows với Copilot CLI bên trong WSL bằng zsh, sao chép 12 dòng và gửi token [Paste #1] đã thu gọn. Vì không có tệp nguồn hoặc bài kiểm thử nào được nêu tên, hãy lần theo quá trình xử lý token dán từ lúc gửi prompt đến request tới model.
