What's Wrong?

When I run OpenCode in a CLI session through PuTTY, opening the command menu with Ctrl+P and then pressing the Down arrow causes raw characters to be inserted into the input instead of moving the selection. The last version that I know which works is opencode 1.2.15. Anything that I tried after 1.2.20 - 1.2.24 are broken

I also see characters being typed automatically when I move the mouse while OpenCode is open in the terminal.

What Should Happen?

There shouldn't be any raw escape sequences
