The shortcuts for jumping to next or previous message not working well wiht long response/message

Description

I'm using OpenCode CLI v2.0.8. I mapped session.message.next to ctrl+down and session.message.previous to ctrl+up. I found if I have multiple responses/messages and some of them are relatively long, then the jumping to next or previous commands/shortcuts don't work very well, they'll jump to somewhere in the middle of the long response/message, not precisely to the next or previous one!

With OpenCode CLI v1.18.31, these commands/shortcuts work better for long responses/messages, but still if the responses/messages for very long, then they have same problem.

But in both v1 & v2, if I use <leader>g (ctrl+x,g) to trigger the Timeline , popup to let me navigate through and jump between them precisely. So don't think there should be any technical difficulties for session.message.next & session.message.previous to achieve the same.

Start by tracing the session.message.next and session.message.previous shortcut handling in the OpenCode CLI, then compare their behavior with the Timeline navigation triggered by g. Reproduce on Windows Terminal with multiple messages, including very long responses, and confirm that each shortcut lands on the next or previous message rather than inside its content.
