[CRIPPLING BUG^2] Pressing backspace deletes two chars

[DamianB-BitFlipper]

Description

Thanks for the hardwork, however I fear there is a weird bug in opencode where when I press backspace, it deletes two chars. v1.0.122 on macos

This isn't a problem in ANY other of my apps, so it isn't my keyboard or something

OpenCode version

1.0.122

Steps to reproduce

Just press backspace.
