Kitty keyboard protocol escape sequences (`[110;1:3u`) inserted when typing prompts

Environment

• codex-cli: 0.80.0
• OS: macOS (Darwin 25.2.0)
• Terminal: kitty
• Shell: zsh

Description

When typing prompts in Codex CLI, kitty keyboard protocol escape sequences like [110;1:3u are being inserted into the input.

This occurs even with enable_kitty_keyboard_protocol no set in kitty.conf.

Steps to reproduce

1. Use kitty terminal on macOS
2. Run codex
3. Type any prompt - escape sequences appear randomly

Notes

• enable_kitty_keyboard_protocol no is set in kitty.conf but issue persists
• Kitty has been restarted after config change
• Claude Code (Anthropic CLI) does NOT have this issue in the same environment, suggesting the terminal config is correct
• Related to closed issue #2572 which was reported for v0.23.0 and later re-reported for v0.66.0

Expected behavior

Normal character input without escape sequences being inserted
