Hi @liunannan01 and maintainers,

I've tested this fix in our production environment and can confirm that it successfully resolves the issue with escape sequences (like ?[C, ?[D) appearing in the input when navigating history with arrow keys.

Question: Is there any reason this PR hasn't been merged yet? It's been open since March 2022. If there are any concerns or additional work needed, I'd be happy to help.

Thanks for the fix! 🙏
