Long text gets cut off and bottom content disappears in the editor

[devslimbr]

Description

When the editor content becomes large (many lines of text), opencode starts cutting the content, causing the bottom part of the text to disappear. It’s not possible to scroll to the end, and the missing text is not visible or accessible.

This happens even though the cursor continues moving correctly — visually, the content is simply gone.
